Syn Attach – 6 Months – Thousands Of Request A Second
Jul 21, 2009
For the last 6 months our site has been under severe brute force, syn flood attack. They keep bombarding a single URL of the server and it is xml file. They are not attacking any other URL.
We have removed the xml page from our site but still they keep on sending requests, this is for the last 6 months non stop.
The IP has been changed just to see and they are sending several thousand requests per second. The requests come from different IPS and different ranges, so you can not even block the IP’s. They seem to be coming from a legitimate IP’s.
Due to this I have had to pay for an extremely expensive server which holds 8 GB of RAM and quad core processor etc, however, even with this the server server still reaches critical level, just because these requests are eating up my resources.
Our technical team has been working on all aspects of apache server security, external modules, firewall, hardware firewall from beginning but still we are not able to stop them.
We have installed following modules.
7) SYS_Cookies enabled
We have worked with the hosting company and their technical team leader, he installed the best CISCO hardware firewall and tried to stop them, but in vain.
We have checked our server to see if anything from our site is causing the request, no extra file uploaded on to the server. For example if some file has been upload or some text has been added to the file (checked if we’ve been hacked). Even though we checked for any hacks, I am still wondering if there is something we do not know about. Can a hack lead to huge amounts of traffic?
We need some help to stop these attacks. We have searched a lot and have found that sites that get attacked like this have only one option is to shut down till it stops. I really hope that will not be the case for us. Please let us know if any one has any ideas to deal with this.
Also could it be our own part of php code which can do this? We are ready to check every php file to make sure it does not have any line of code which can be dangerous?
We worked with hardware firewall company to drop a request on the spot coming for the single URL but it is getting setup.
We have antivirus running on server however if any specific antivirus or antimalware is needed, we can try that.
Following are the details I have got from my linux admin. This will help you to trace the issue in better way.

I am running a very successful wiki based website that has outgrown our current web host. The site runs very slow because our host says we are hitting the memory limit on the server (currently under a shard hosting plan).
Thousands of visitors per day Ten thousand page views per day (all PHP) 20GB bandwidth per month MySQL database
I'm trying to tar a folder that has 100's of thousands of files and I ensured that no files are being added or modified in that folder while the below command is being executed:
nice --adjustment=20 tar -cf users_from.tar users_from
I've tried it multiple times and it always stops before it finishes and ends up with a corrupted .tar file which gives errors when extracted and is obviously missing a lot of files. Sometimes it creates 200+ MB, sometimes 50 MB before it stops.
I also have enough RAM + swap for the operation so that can't be the cause. So is it just impossible to tar a directory with so many files and is it even possible to get a list of the files in that directory?
My sever is running mailscanner-4.56.8-1. Of late many of our customers complain that mails send To and From our server take hours to be delievered.
I tested this myself by sending test emails to and from my hotmail account which took long time to be received and delivered.
Also, in /var/log/maillog i see entries such as the one below; "Jan 4 20:39:36 www MailScanner: New Batch: Found 17678 messages waiting "
So i understand there is about 18 thousand emails in MailScanner /var/spool/mqueue.in folder.
To test i stopped MailScanner and started Sendmail, i send an email to my hotmail id and it got delievered immediately, but when i restart MailScanner and resend the same message it took 20mins to get delievered.
- how do i improve MailScanner processing so that messages are delivered faster? - Do i need to change the "Max Children = 5" variable in /etc/MailScanner/MailScanner.conf? - how do i force delivery of the 18thousand emails in mqueue.in folder?
I am having problem with a server. On all sites on the server start appearing core.xxxx files that in result fill server. Quotas were disabled because some people had issues logging in on because of error.
Sorry for the inconvenience!
The filesystem mounted at /home/*** on this server is running out of disk space. cPanel operations have been temporarily suspended to prevent something bad from happening.
Please ask your system admin to remove any files not in use on that partition.
how to remove all of them so they dont appear again, on some sites there are thousands of core.xxxx files and weigh over 60GB.

Well I have to say to begin with, I never expected to be with one provider for so long. My sites are low volume enough that it would be a waste for a full dedicated server, but I wanted the control that a VPS provided.
Four or five years ago, when I first started trying to find a VPS, I floundered. Fpund more problems, and slow unreliable servers. I averaged about 3 host a year during that time. It was at this time I started reading about XEN, and the concept of it's method of virtualzation intrigued me, so I started searching for a host that offered this type of VPS.
My first experience was a big let down. Not really sure what the problem was, and cannot remember the name of the host, but that server was extremely slow.
It was then that I came to WHT and found the VPS offers here. There I saw an offer by ServerDave, signed up only to find there was a waiting list for new VPS. It originally took about a week (to my initial disappointment) to get provisioned. The VPS had 1 gig of ram allocated that was almost unheard of at the time. As soon as I started setting up I could tell the difference in speed and responsiveness.
I did have one problem, contacted support about it, and it was fixed within a couple of hours. Turned out to be a php misconfiguration. That was the last problem I ever had with my VPS. All my other contacts with support has just been a few general questions, and of course once to upgrade to a new VPS (newer OS) wich they provided me more than enough time to complete my move.
For most of the time, the only graphs they offered were network graphs, but just recently they have performed an upgrade and the graphs now chart - cpu - disk utilization - along with the network charts. For a control panel I chose DirectAdmin, which I now love. And 5 dollars a month is a great price for it.
Uptime has been terrific. In my three years, my server has only gone down about four or five times for a short time. These all were for upgrades that was well announced before the downtime which was usually just a system reboot for a kernel update.
I use CentOS, and they do auto yum updates which makes it nice. I update my server software manually through directadmins custombuild scripts.
They do have another control panel for auto OS reloads, but this of course does not install your control panel. This is why when I moved from CentOS 4 to CentOS 5 they provisioned another VPS for me (free of charge).
All in all this company has been a pleasure to work with. I look forward to the next 3 years with them.
cant believe its almost been a year already, but like sand through the hour glass so goes the days of our lives. anyway, my almost year with imountain has been one of pure bliss. everyone on the imountain team needs to be commended cause they have consistently been there when i needed them and have truly bent over backwards to answer any remedial question i may pose or fulfill any request without hesitation. their support team is phenomenal and have truly gone above and beyond the call of duty and it has been truly appreciated.
uptime has been excellent. there has been only a few hours of downtime and most of that has been scheduled. even though they had to shut me down last week, but i truly couldnt be mad at them cause they did everything they could to rectify the issue. i run a music blog and some spider/bot was trying to download everything in my directories at one time which of course brought/slowed down the server i am on. i could tell that they hated taking me down, but business is business and i know i was affecting other people's businesses. in the end they tracked down the main offender and everything returned to normal.
in regards to speed, i think my site loads pretty quickly. i have not been told otherwise. people are quick to complain about other stuff and loading times has not been one of their gripes.
all in all i would give them a 9.5 out of 10 and will continue to recommend them to anyone who will listen.
I'd been with hivelocity for 14 months by now and i'm thinking to continue my bussines on there.
I created a thread on the past, this is the thread:
And this is what i said:
What can i say?
They just Rock, Dave and steve are just great.
Dave is my account manager he is helpfull, quickly and very efficient.
i would like to recommend people to join in hivelocity.
They are just more than fine, my server is working great and i had 2 issues resolved.
1 issue in less than 20 mins (another server in the rack was consuming a lot of bandwith) the other issue was a little more complicated but it has been resolved too, thanks Dave
They have the same problem with support than sharktech (not managed), but if you talk to your account manager or Steve they will take care of it and get the problem resolved in a few minuts, that's just cool.
Service and support for me was really good in one week with they .. i will stay for a long time here if everything goes right.
and if we can, stablish a long term business based on trust (i'm a coder i can help)
Well from that moment to now i can say the following things:
No downtimes, only schedules (maintenence)
No support problems.
I upgraded my server to a quad2core and for 6 months payment, they gove me a second HDD!
I'm sending new customers to hivelocity right now, and trying to start reselling their servers.
¿why do i want to?
Because Steve and Dave, are responsable guys.
Because Network works fine.
Last server i bought for a customer: 1 day setup, no problems. I did a hardware check and it was OK, no HDD failures and TEMPERATURE was the right.
Because they understand if you have a problem.
Because support is there to help, even if you don't pay for "Managed services"
And i think that, they manage customers as well, that you can feel as a part of the company and not just another Argentinian customer.
So, watching the huge financial crisis, i want to give a good review about this company, and try to get more and new customers to they.
I would highly recommend to buy their services, this is not another company this is one of the best companies i ever knew.
This is my first review regarding a dedicated server prodiver, so forgive me if i miss anything.
We are a small web hosting company located in Greece and after many years in a Greek Datacenter, we were seeking for a reliable provider with Managed Dedicated servers. After a lot of search here in WHT, we came through ServerBoost which is located in Holland.
Sales: Jelle was very patient during our talks, although we were just researching at the time being. A really nice guy and a true professional, answered all my questions as I was skeptic regarding the migration, or details of our contract and service. ( personal fears :p )
Support: They say the first impression is the most significant and I must admit that mine was pretty good. Starting from the Server migration ( From 2 old/slow servers to a brand-new Dell one. ) which went really smoothly from ServerBoost part, taking the downtime to minimal time!
Our SLA contract has a specific time window for support requests but it hardly takes over some minutes or 1-2 hours to get a response ( regarding the time of the day of course! ) and Jelle is always there when i need to ask something.
Hardware/Network: Our Dell server is running really good, and the network is really reliable as "promised". Good speeds and ping ( from Greece ) which is important for our customers.
Conclusion: For me, having dealt with only one foreign company in the past for hosting ( US ), ServerBoost is the ideal one to do business with, because they look really "caring" about our business and their flexibility is priceless.
I'm looking forward using ServerBoost for a long time, really satisfied! :-)
I would just like to say that they surprise me for a shared host.
Although I pay quite a bit I still think it's worth it. About $15/mth for 15GB HDD and 75GB transfer. My website handles ~300K hit's daily with only a few hiccups. It's uptime is something like 99.97% which is decent. The only big incident is when I first signed up I was transferring my domain which took a few days, but was resolved professionally. So far it's a big thumbs up.
Decided to give a VPS a try back in November. Ordered through one the sales advertised in the offer forums, got set-up in less than 12 hours.
In terms of performance, the VPS works fine.
In terms of service, this is where the ball is dropped.
The issue is that they set me up in LA, and I'm on the East coast. So I've contacted support, asking if a move was possible. When they said yes, and I've confirmed that their offer to move it during the night was fine, I've even shut everything down to make things smoother.
The next morning, I receive an email telling me I will get another one once it's done... the following day, I receive an email that it can't be done, as I have a x64 OS and there is no space on the node.
So I let this slide, and decide that sometimes you just have to bite the bullet and decided to offer them to BUY another one, this time on the East coast, if they could offer me the same setup as I have on the West coast. They've agreed, and I did the order as they requested... That was around noon 2 days ago, and still nothing today...
For another example, I've requested a ticket because the /dev/tun wasn't configured properly in the container... I don't know what they did, but it corrupted my VPS so bad that I have to re-initialise it completly. Another example: I've posted a ticket that their gentoo image is faulty (no network support at all!), and to my knowledge this was still not fixed.
So yes, NYNOC has some cool ideas like an online chat, even offered an EYEOS desktop, forums, tips, and great prices... but for me now this ain't worth it much and will be canceling my accounts. I guess coming from VPSFarm has spoiled me (instant setup, quick support), and will be looking for a new provider.
I used 15 days of godaddy's shared hosting before FsckVPS. Due to unexpected traffic, I had to move to a VPS. So I chose FsckVPS's 512mb packet.
I was very sattisfied with them. Their servers were fast and the VPS got setup in just a few seconds.
The hacking incident happened this month. I was still pleased by the way they handled it. So I decided to stay with them. They decided to give 2 months free after the hacking incident.
2. Month and 3. Month
Everything was very smooth, running perfectly. Servers were still fast after I got switched to a new one after the hacking.
This is the second time I paid to FsckVPS and I was pretty happy about it.
Then I have been informed that they will be switching servers. They told that it would take around 4 hours per vps.
So when I noticed that my vps was down for the first time, I didn't react and waited. After being down for about 8 hours, I sent them a ticket. The response came after 4 hours saying that it was now online.
I logged in to my vps and the first thing I noticed was how SLOW it was. After a while, it crashed and I couldn't reach to my vps anymore. I sent a ticket, they reset the server, it got a little better.
This happened about 4 times. Everytime I sent a ticket asking why this is happening, I only received a response saying it is OK now.
After 3 weeks of being like this, I decided to switch to a new VPS provider.
Now I am on my new VPS provider, hoping for better results.
My fsckvps will expire in 4 days and it is still very slow.
After having a dedicated server for more than 70 days from WiredTree.com, I thought that it would be a good time for a review.
I came across them through good reviews in this forum and took the opportunity to get one of their special offers (Core i7). As a short summary in advance: I can fully recommend them to anyone seeking a managed dedicated box.
Sales: I just had contact to Sales twice - Once as I tried to bargain for an even cheaper offer than the special one they already had (without success, by the way) and a second time when it came to an eventual server upgrade. Response time was quick, the answers were professional and friendly and there is nothing I could complain about.
Server Setup: I was in a totally different time-zone than WiredTree while ordering the server. As they have the practice to call their new customers for identity verification, the call reached me at night time and I could not pick it up. So I called them in the morning and they called me back again. It must have been deepest night time in Chicago at this moment. From this telephone call on, it took less than 2-3 hours (as far as I remember) until the server was ready and online. Another thing is their "ServerShield Server Hardening" that they perform before you get the box. I never received a dedicated server before with so many tweaking measures taken in advance. MySQL performance was improved, the firewall was well configured, security checks were already made, everything felt fine-tuned in advance. So, again, very good job done by WiredTree.
Hardware Quality: You might say: "You've only been with them 70+ days. Of course, there was no hardware problem during that short time". Well, I read here at WHT about customers of other hosts who had the first failures already at the moment they received the new box. So - No hardware problems at all until now.
Support: I am not very experienced in server management and tend to get nervous if something doesn't work and support takes more than 30min. to answer questions. I know that this makes me annoying sometimes, but at least I always try to be friendly. Fortunately, WiredTree seems very good prepared for nerve-wrackers like me... Support never took more than 15min. to answer my requests and in at least 2 cases, they even bent backwards to help me with problems that had nothing to do with them. Every single request got solved in a very short time. I contacted support at the most unusable hours of the day because I often travel between different time zones - They were always there, like an own IT-Crowd in your pocket. Two thumbs up for their support staff.
Network: 100% Uptime during the whole time. No hickups at all, no problem that I would be aware of. Fine speed all the time. There is really nothing negative that I could say.
Billing: No billing issues at all. Everything worked correctly.
Their customer portal "Grove": Well. Hmmm. Okay, one thing first: I saw several customer portals during the last 10 years. And none of them blew me away. I haven't seen SoftLayer's yet and was told that theirs should be even nicer than grandmas cheese cake, but the grass is always greener on the other side as long as you have never been there. Let's say that "Grove" is surely one of the better and nicer looking customer portals around. It bundles a lot of information and offers a good way of communication. The rest is a question of taste...
The bad news: I cancelled the server today. The company I work for has rent several servers at another host and paid them 1 year in advance. One is totally unused (great planning, MnMgt!) and I was offered by my boss to use it cost-free for that period of time. Well, this is an opportunity I have to take... Saving $300 a month is quite a lot of money. But I am determined to go back to WiredTree as soon as my "free time" is over.
I've been using SmoothVPS for about 4 months (and colleagues of mine have been using them for more than that) based on posts from WHT as well as recommendations from others in the industry. Bob @ SmoothVPS has been extremely helpful, very responsive, and is seemingly always online to help me with even the most basic of questions. He has bent over backwards to accomodate my random needs and helps me with specific server configurations that I can't figure out - even with third-party packages that he is not required to support!
I have three Linux-based VPSes with Bob and he has no problem configuring them to my specific needs with whatever version OS that I require. I plan on adding many more as I migrate all my servers to him - I've decided to give him my exclusive business due to how well everything runs and how competitive the price is. Billing is simple - Paypal subscriptions or regular invoices make it a snap to manage (even if I lose track, which I do - sorry Bob).
The bottom line is that SmoothVPS is the place to go for your VPS needs. I haven't needed Windows boxes there, but I will probably mess around with one in the near future to test some software. They're moving to a new DC in the near-future - and they're giving me 30 free days of IP migration to make sure the process runs smoothly. Just amazing.
I've had a Krypt VPS for a few months now, started with the VPS400 package and moved up to VPS800 over time. Initially (I'm guessing they had just gotten into providing VPS's) the service was EXCELLENT! My VPS was located in their LA datacenter on the Level3 backbone. First two months the VPS was rock solid, I was running a full LAMP (no optimizations) install along with Webmin. By the 3rd month I started having issues with sluggishness, both on the site and SSH. Put in a support ticket which got responded to within 10 minutes as usual (fantastic support!) and their techs moved my VPS to a less loaded VMware node. Things were again pretty solid for about two weeks, then the same thing happened again. I let it be for a few days thinking it may just be a spike, but even after a week it was still pretty horrid. I had even turned off the LAMP install and Webmin in favor of a lone Lighttpd install to serve static html pages. Mind you by this time I had been upgraded to above their VPS800 package, yet I was still having performance issues. Put in another ticket and asked to be moved to another node, they said sure and asked a timeframe, I told them asap and let the issue be. After 4 hours of not hearing anything back, I update my ticket to find out that they were having some issues with the VPS, ok bad things happen, give them time. A few hours later I ask again and am told that they formatted the VPS without any authorization from me...Its a VMware host, they could at the least have attached the virtual hard drivei mage to the new install of my VPS, but they prefered to just delete it. I run several ESX servers at work and even with a nonbootable (according to them) image, the hard drive can still be mounted and recovery can be attempted. I was angry but I have a few dedicated servers with Krypt so I gave them another chance. I took the freshly installed VPS and started hunting down backups to restore from. Installed LAMP and Webmin, gave it a week and once again: slow. I'm fairly certain that CentOS repo apps and Webmin arn't enough to cause a VPS to dog down this bad, even with *everything* turned off (top shows 24MB ram usage) SSH and pages being served by lighttpd are taking 3-10 seconds to come up, as before they came up before I even let go of the button.
Ratings Support: 10/10 Service: 6/10 VPS Quality: 5/10 Network: 5/10 (great in the beginning, after a week less than 400KB/s)
Overall they're a great provider, but they need to monitor their nodes more carefully and find abusers. It seems to me like they're either overloading their nodes or have something misconfugured thats causing issues. I was told a few times to restart my VPS which didn't help at all. Orderded a VPS with them about 2 weeks ago on a different account, havn't even touch it since I got it, as of right now, SSH is sluggish, apps like top take an average 5 seconds to come up, max throughput is ~300KB/s from Seattle (hit ~7MB/s when I first got it). Same issue as my other VPS. I'll provide my domain to the mods for authentication.
I thought I could share my opinion on VolumeDrive after being with them for a few months. I always appreciated when I could find in-depth reviews from hosting companies when I was looking for one so I hope some peope will find this review useful.
First of all, here my plan with them:
AMD Athlon64 3200+ 1 GB DDR2 Ram 120 GB SATA Hard Drive 3000 GB of bandwidth on 100MB port 2 IP addresses Ubuntu Server 8.04 Linux
This package costs me $49.95 per month.
It all started when I contacted them to have more information on their services and what they have to offer. They replied very quickly and sent me a document detailing every offer they have and how their plans work. It's a shame that all that information wasn't available on their website, they proposed roughly 3 different dedicated solutions on their order form when you can actually choose a bunch of other options. Anyway, I asked a few other questions (like if they could install Ubuntu even if it wasn't listed in the available OS, and they had no problem in doing this). Again, they replied quickly. I made my choice and as I made my first payment, my server was online 24 hours later, as stated in their e-mail.
Communication with Volumedrive's staff is always great, I've had an issue one time where my internet connection was realllllly slow. I e-mailed them and it took a few minutes before I received an answer to my e-mail with someone trying to find what was wrong. We exchanged a few e-mails trying to find what was the issue and the issue got resolved in no time. Aside from this problem, I've never had any network or hardware issue (still have a fresh new server though)
I also personnaly think that their prices are far superior to what other companies offer. Their plans are flexible and if I want a hardware upgrade for example I know I can just contact them and we'll work out the details.
The only downsides I can give them is that their website is missing a lot of information. When you are looking for a server you may not want to spend time contacting each company by e-mail to ask question and have more information, you rely on the website to give you a lot of details. Also, their invoice system is not so great. You receive an e-mail saying you need to pay them and they only accept paypal. When your payment is done, you don't receive any confirmation e-mail. It's not bothering me much for a 50$ server, but I'd want a more conventional billing system with automatic renewal if I had a big business going on with them.
All in all, I really like volumedrive! I'd recommend it for everybody looking for a low cost dedicated server, they're fast, professional and helpful. You just need to send them an e-mail to get the plan that works for you so tow thumbs up for Volumedrive!
Pricing: A little more expensive than some other NL hosts but you get what you pay for.
Setup: Total setup time was 3 days after payment (the server was a custom setup), because we had to wait an extra day for the setup Jelle gave us a free upgrade (better CPU and HDDs) which was amazing seeing that the setup period wasn't that long anyway.
Uptime: In the past 7 months we have had 2 small bits of downtime, 1 was scheduled - when they upgraded their datacenter and the other was due to a RAID card failure, which was promptly replaced in less than an hour. Their network is faultless.
Support: We only have the free SLA yet Jelle responds within minutes, and his responses are always friendly and professional. However I haven't needed to contact support outside of business hours so I cannot vouch for that, but during business hours it's top notch.
Overall: I can't recommend ServerBoost enough, I'm 110% pleased. We/I have 5 servers in EU each with different providers and ServerBoost is by far my favourite and the one I recommend most.
I'm sharing my experience with Dynaceron till now .
I wanted to try a Linux server and I ordered one of their hardware, that came with CentOS. I have had many questions about Linux, as I am new to it, and the friendly tech support people helped me find answers. The questions I had were often answered in under 3 minutes. I've had 5 minutes of downtime, but that was because I ordered a 4 gigabyte ram upgrade.
I decided to go back to Windows and I asked them if they could install Windows on my server, They asked if I had my data backed up, when I said yes they said they were going to start the install ASAP, after 1.5 hours I received an email with the login details..
After 15 days I asked if they could upgrade my uplink to 1Gbps; The upgrade was done without a server reboot.
No problems so far, everything has been going well. Seriously, in my opinion they are the best service around, couldn't ask for better. Their uptime is fantastic. In 3 months I've only experienced 5 minutes of downtime, but again that was because I ordered a hardware upgrade.
I would highly recommend them to anyone that is looking for Quality hardware and support.
I will write a review back in 3 months or if I ever experience a problem I will update this thread.
Finally I managed to get some time to write another review about my host, VPSRight. Simple summary, one of the best webhosts that i have ever had. With great support and resources. And the best thing is they think about their customers.
Talking about their support, they're an excellent bunch who knows what they are doing and what they're being asked. Extremely prompt on responses and are usually responded within an hours time. In the initial month or so I've submitted a lot of tickets and they were dealt with ease.
Their servers are great and fast. Not overloaded and recent uptimes have been great. For the last 3 or so weeks I've had no downtime. And after switching from FluidVM to SolusVM the host nodes have become much more stable.
Network is also great and have a good connection speeds. I rarely go below the 1Mbit/s when downloading files to the server (incoming). A few weeks ago we had a small issue of packet loss for a few hours, as result of a DOS attack on another server at the DC. It was soon mitigated and services was fully restored.
In the months of June/July, VPSRight inured a lot of downtime due to DC migrations and s/w migrations. Therefore they made the next billing cycle free to all it's customers as a compensation. This something good as host and they've taken responsibility for the actions they took.
Now everything is a smooth ride and I am a very happy customer of theirs. I'd happily recommend them if someone is looking for reasonably priced, managed, decent spec VPSs.
I think Zinkhosting.net does not get the credit it deserves. In the last ~7 years I have been with many different hosts, and I have to conclude that Zinkhosting.net has been the best. From day one I knew this company wanted to serve the customers, and the small size allowed them to do so. Many large companies ignore the customers when it comes to reliability, price, and support. With Zinkhosting.net I did not have any downtime, and the prices were great compared to other companies. The main reason I stayed with Zinkhosting.net was the support I received. The owner himself was able to help me out on many situations where I did not understand why a certain script was not working. Even though he did not have to offer this sort of support, he still did so out of courtsey. I hope Zinkhosting.net can keep on serving my needs in this manner.
I've been seeing alot of negative threads about Hivelocity so I decide to post my review.
A little more than 4 months ago I ordered a server on Hivelocity using an offer they posted on twitter, it was a Core2Duo for $75/month and first month for $50. I ordered on the chat and the sales told me there wasn't any package with the Core2duo so he used the next cheapest server to order(Core2Quad q8200, everything else was the same) and wrote a comment saying that the actual server would be a Core2Duo.
I paid the bill, submitted some documents(on June 7) and waited, I had to send a few emails because there wasn't any progress with my order and by June 10 the server was live. When I logged in I realized I was given the Core2Quad q8200, same specs, better CPU
Ever since then I've not needed to talk to support for anything except adding some services(extra IP and 100mb port, both were quickly added and with no problems).
The story begin at 13th January when the first time i put an invoice there, at that time they offer Semi Managed VPS (reselling from santrex). Support ticket was answered not more then 12 hours and all of issues were solved really fast. except when i order my 2nd vps which take almost 24 hours to be provisioned, but still it's really reasonable.
@ 24 Feb, i got an email stated that they're launching their own node and offer me a special deals, of course i said yes. and it's become fully managed VPS. After i moved my 2 vps to this new node i was never ever submit a single support ticket until now and never had a major issue. i got only one downtime not more then 10minutes when the node got kernel panic, that's what they said on live chatt.
Live chatt support is really friendly and helpful. the server speed is fast, i use these vps for VPN and got no complaint about the speed from my clients.
I have 2 Basic VPS with them. and very happy with it.
4-5 months ago my website was in desperate need for a new hosting solution, I looked around on this forum and found iWebfusion.
They offered a discount back then that allowed me have a onetime discount.
I signed up for their "Pro Plus" VPS which costs $40,- a month and added as a comment that I needed to get up and running fast since my website (which is fairly popular) already was down for around 3 days.
I chatted with Nikolce and he promised me to get me setup ASAP. In less than 6 hours I was up and running (Not counting the DNS propagation).
To be honest I wasn't sure what to expect from them since they offered a very powerful VPS against only $40,- but I was surprised positively.
In the 4-5months that I was with them they answered every ticket very fast and with skilled correct answers.
Overall I would rate them an 9/10.
I won't rate them an 10/10 as I sometimes felt that my VPS had more speed to offer...but didn't, later on I found out that my CPU limit wasn't raised as Jacob from iWebfusion should have done, he sincerely appologized later on for this issue but it didn't really matter...and humans make mistakes from time to time
I'm not with them anymore since I'm a guy who likes to try out different company's and services (that's also probably why I have a thread here with problems related to La(m/n)ehost).
Also my website grew out of VPS services and I wanted to try out a other company for a semi-dedicated solution.
I signed up with MediaLayer [url](ML) for my client in November last year.
I've read a lot about ML here which are mostly (all?) good +ve reviews & so I decided to pick them to host my client's site.
Since the website is an ecommerce site based on Magento, I needed something that could handle application load. Its for this reason I chose ML.
Magento itself is pretty slow the first time until cache starts working.
So far its been smooth at ML and this post is just to add to the pool of its +ve reviews on WHT.
There was just one unexpected downtime which lasted for a few minutes. It was the mysql server that was down, not the http server (litespeed).
You dont get a whole lot of space at ML, so hosting a lot of raw data like images can be pricey - most of the space taken on my client's site are product images - and duplicated in cache for every dimension by Magento. As of now it gets 500-1000 pageviews a day but this is to increase over 10 times this year and if it goes beyond shared hosting limits (which I doubt), we'll move it to ML's VPS.
