I use a VPS with CentOS and LX-Admin. My VPS run only 1 forum phpbb3.0.2 and nothing else.
3 days ago, disk used was 2.6GB, yesterday disk used was 2.7BG and to day disk used is 2.8GB ...
I wonder why disk used of my VPS increase everyday? It's may be because of cache and log? How to clean unnecessary cache and log?
has anyone else noticed an unusually high load occurring from 9 till 11 EEST time on their servers?
I've been getting high loads everyday this week at exactly these times.
I'm thinking that this is a crawler/bot that is causing the loads, i've already installed dos deflate and there hasn't been more than 100 connections from the same ip, so I'm ruling out any DOS attack ... besides, what kind of attack only takes place for 2 hours a day at exactly the same time?
I'm on a cpanel system and would like to know which logs to take a look at to determine the cause.
I have a problem with hoster. Purchased virtual hosting. All worked fine for more than a year. I did not make any changes in websites recently. Last several days one issue appears constantly: website starts downloading very slowly (30-60 sec for 20 kb page, or connection timeout). And each day their tech support don't realy want to help me. Only after 3-4 emails they fix the problem, but on the next day the problem arises again. I suppose they just ignore my problem. Possibly server is overloaded by other sites, or software was not tuned correctly, or something like that, and hoster does not want to solve the problem.
What can I do with this hoster?
I have a dedicated server with many websites on it. The problem is that I got very high load every day in the midnight I checked all "my" crontab and they are all fine. I even stopped them but nothing changed. My backup time is not the midnight, it's about 6 AM.
I tried everything I could but everything still like before high load every night.
For the past two weeks, our Hypertown RedHat RHEL 5.2 server has been going down everyday because of a wierd Kernel Panic problem.
Attached you can see what was displayed on the console at the time of the panic. This is what SoftLayer tech. support team was able to obtain from the console.
We are not using Samba or NFS-based applications.
Here is the server's info:

In your opinion how much downtime is too much downtime?
1, 2, 5 hours over the course of a month? 99.8%, 98%, 95% total uptime too little?
I mean I can understand technical difficulties and I am willing to be patient with my host especially when the service (when it is up) is good but where exactly do you draw the line, start asking questions, or canceling that contract and demanding your refund?
i have 150 domains my server I wish it to migrate to a new server I can do restore domains, mail and users and data, stats to new server. I need minimum downtime so I need your's advice step by step which service need to restore first so my user get minimum downtime.

Moved to them recently from Wiredtree as my clients were asking for a uk-based server. I am a small time host, mainly to friends and family.
I've had more downtime in a week with VPS Ville than I ever had with Wiredtree.
i've recently been experiencing a lot of apache downtime on my eUKhost VPS. anyone else having this problem? it's driving me crazy and i'm thinking about moving.
View 7 Replies View RelatedRecently our provider has been having unplanned long outages (along with a complete server move that took several hours). This has turned out uptime statistic from exemplary to mediocre (100% to <99%).
As we are a hosting company and normally have an extremely good amount of uptime, when is it time to give up on the provider? I am extremely concerned this will become regular and our uptime will simply continue to go down the drain, however, they have been good and have been the main attribution to our 100% uptime (along with our great technicians and hardware).
It's not even been a month that I started subscribe a windows 2003 VPS hosting with them and now their website is gone and I am unable to access my VPS server
View 9 Replies View RelatedI am the webmaster for a high level court system. We run mainly .php and MySQL like most do. We are in the process of doing a transfer to 1 and 1. I want to be able to test everything (database wise) before I do the transfer. I thought the best way to do so would be to purchase another DNS name and server and transfer everything there first to test and then when that is fully operational have a redirect to there and do the DNS name transfer from the old site to 1 and 1, and when the DNS name is on 1 and 1 take the redirect off . I don’t want any downtime at all.
This might not be the most cost effective but for downtime I thought it would be the best way, especially when I can have a live test before the transfer.

In the forum here i put a story about when i was changed to vz45 from vz69 some months ago and the problem is growing. One month ago, around 1/oct, was a half day.
Yesterday i detect a problem at 08:40 am aprox, and they are working in that but something is AWFUL here.[url]
I have many domains and webservers. so it's hard to monitor everything usually. i heard there are some websites and softwares to do this.
does windows 2003 have anything default like this ? or can anyone suggest the application for my windows 2003 server? which sends alerts if any error is going on my server?
Also there any other websites which is doing this monitoring? because i have some shared accounts and i want to monitor it too.
I'm having a bit of a quabble with my current host because our server was unreachable for an extended period yesterday, and since I made a traceroute that arrived at their datacenter but not at our server, I was assuming it's a crystal clear network issue.
Today however they tell me that a traceroute means nothing. To quote them:
Quote:
Please note that having a traceroute end prematurely does not always indicate a problem with the network it ends at. Being that traffic is typically asynchronous, the return path back to you does not follow the same providers. Your traceroute can not fully take into account network connectivity issues on the return path nor will it show them. You would need a traceroute to and from the server at the time of the issue (while this may be impossible if the server is down, opening a ticket immediately and informing the technician you would like a traceroute to X.X.X.X IP would hopefully catch the return path issue).
What do I make of this? First time I've heard that, when the network is down, I need to contact my host to tell me. But without any polemic - is this what it boils down to?
It is probably acceptable for a site on shared hosting to have some downtime. However, how much is acceptable?
According to Pingdom one of my sites had a total downtime of 14 hrs for Feb. One time it was reportedly down for 4 hrs.
I had set it up to ping every 15 mts. Are these results trustworthy? And if it is should I move my host? Or at least tell them to move my site to another server?
The reason I ask is because I was wondering if this was the norm for shared hosting.
Probably been asked a million times but after spending 30 min searching since the limit is 130 seconds between searches... Anyway, i am VERY unhappy with ModVPS as my server keeps going on and off and on and off and they tell me its "fixed" but it keeps doing it to all of my staff even... anyway enough of that
I purchased a really nice dedicated server and need to know how to migrate all accounts over without having any downtime and allowing people to still use their website as normal. I have about 60 clients and would hate to see one of them upset because their data was lost during propagation when they connected to the old server instead of the new, exc.
Is the best method to setup a cluster through cpanel? Or is there a better way?
I have a server that used to be with Hostgator. There is a hundred accounts and the average load is 0.5. It has 2 gigs of RAM, a Dual-Core Pentium D and 2x Sata HDDs in Raid-1. At one point it started being very often (at least once a day) down. It would be all of the sudden down. I used to monitor it, with 0.2 load average, and all of the sudden, the connection is lost, I can't access the web sites, etc... Fed up, after several weeks pressuring over Hostgator, I cancelled the server, I contracted the same configuration at Softlayer and contracted TouchSupport to manage the new server. They migrated the hundred web sites to the new server... Exact same problem. Every single day, any time of the day the server is down. There's no specific time. And right before it's down, load average is below 1. From the logs, there's nothing unusual. Softlayer changed the CPU and RAM just to make sure. Same problem. It's been a month like this, and I just don't know what to do at this point. Moving to yet another company doesn't seem to be a solution I think. If it were a DoS, load average would be very high before going down, but it's always very low right before. Do you know what may be causing it?
View 14 Replies View RelatedI colo a 1U machine with 2-36gig drives. They're not in RAID, and I have it set to rsync backups to a remote machine on a regular schedule. I have another remote machine functioning as a secondary DNS. Neither of these 2 are on a large upstream pipe. I just bought 2-147gig drives that I'd like to replace the 36g's with. How does this sound for a scenario to accomplish this with little downtime (pre-pardon my noob'ish ways):
1. Do a complete rsync of the filesystem to my remote machine as well as sync the mysql db's (to 1 remote drive).
2. Pop that single rsync'd drive into an external enclosure.
3. Travel to datacenter, once there, plug external drive into laptop and start up a VM that boots off of that drive.
4. Sync again so external drive has the most up-to-date data.
5. Change over IP's from colo to VM on laptop.
6. Shutdown and swap out drives in colo'd box with the new ones.
7. Setup new drives as RAID 1, install OS, then rsync filesystem over from laptop to new drives in colo'd box.
8. Change back IP's.
What am I missing, or is there an easier way without a 2nd colo/dedicated server? Currently, the colo'd machine is using about 1.3Mbit/sec outbound and it's running a low load.
has anyone who is hosting a site been sued because of downtime or lack of service? I would love to hear any and all horror stories!

The thread I recalled seeing was about someone hosting shoutcast servers and they wanted to migrate and there was a way they did this without any downtime.
I can't remember the details but it had a way to redirect all traffic to the new machines. This would be great, as I also want to direct all traffic including mails (not just HTTP).
like to clarify this is not a post to bash liquidweb.
I have been a loyal customer of LW for the past 2 years (almost)
My websites have been down since Thursday 3:00 a.m due to "DDos Attack"
on Friday night, the network engineer told me the "DDos Attack" has stopped and problem should have been resolved. However, no websites were accessible.
On Saturday, I ensure you I have made many phone calls to Liquidweb dedicated server support and try to resolve this issue. (Never once did I raise my voice and they were being very polite.)
I believe the server admins that were helping was at the end of their shifts and every time I try to make a phone call to the person that was assisting me to get an update, liquidweb would tell me that he has gone home. Every time the server admin finishes his shift, the support ticket is not assigned to anyone else that is working until I make a phone call to them stating my problem.
I own quite a few large sites that generate over 3 millions hits per day and every hour of downtime means I will be losing valuable clients and revenue. That is why I am extremely frustrated with the 63 hours downtime as it seems like the results of working hard for the past 2 years is slipping away from me as the clock keeps ticking.
I am sorry, I am just trying to share this with fellow webmasters as I really need a place to express my feeling. (None of my friends will understand online business.)
Again, I am not bashing liquidweb...I must have really bad luck myself.
How would you migrate a highly activate mysql db to another server without downtime.
I can easily point the IP in the script to the new server in 1 second.
However, how to physically move the DB instantly without downtime?
I don't like the idea of export, import and then point IP.
Ive looked for a long time now trying to find the perfect tutorial to migrate my clients (on cPanel) to my VPS without downtime. Every tutorial i found doesnt tell you how to make it so you dont have any downtime at all.
I know you can point the DNS from the old server to the new server by editing it through cpanel but i have more than 100 clients and it would be DAMN annoying to edit every single one of them one by one. Is there a faster way? Anyone have a tutorial that i can follow?

If you are using Burst.net do you experience downtime like I'm am experiencing.
