Multiple A Records For Website -- Client Does Not Reach Web Always
May 29, 2009
I have had multiple A records for a website for years, i.e.
www.mywebsite.com => 1.1.1.1, 2.2.2.2
Well 2.2.2.2 has been down for a few days due to technical issue. So I just figured "well i got some work to do this weekend to bring it up, no rush". Turns out that customers are calling and complaining "I couldnt reach your website yesterday for a few hours".
I am seeing no problems personally, but some customers are. I dont think the percentage of customers is very high but there are so far a dozen or so complaints.
Any ideas on what I am doing wrong or where to start looking? I thought the major browsers (i confirmed with four clients they are using IE) would try 1.1.1.1 and then 2.2.2.2 or vice-versa. But apparently that is not happening. I dont think the TTL makes a difference.
What could be set up wrong or is this to be expected ? (and how to improve for future?)

I have been trying to setup SPF records for all of our hosting servers but need some assistance.
Lets say we have three servers with the following RDNS:
ns1.server.com
ns2.server.com
ns3.server.com
Would we create one SPF for server.com and add it to the DNS zones on each server?
Or should we create a separate SPF for each server?

Right, I have my email address (say email@domain.co.uk) connected to my DirectAdmin controlled server.
I have an the simple email services provided by 1and1 that I haven't used for ages.
I am a bit confused how multiple MX records can be used, so far I have edited my DNS record file for domain.com to look like this:
Code:
domain.co.uk.14400INMX5mx00.1and1.co.uk.
domain.co.uk.14400INMX10mx01.1and1.co.uk.
domain.co.uk.14400INMX0domain.co.uk.
If im not mistaken the above show the email server domain.co.uk is connected to (domain.co.uk) is the primary server, with 1and1 2nd and 3rd.
However if I changed the priorities all to the same value, i.e "0" would that mean the mail is delivered to all?
My ideal solution would be, if the primary server was down, send mail to secondary, but that leads me to another problem. When I want to check mail with Thunderbird its connected to imap.domain.co.uk and not imap.1and1.co.uk, so the problem now is mail split over two servers....! I would like a redundant system, to ensure email is online 99.999% of the time.
So my question is, what are peoples current solutions with multiple MX records, and how have they achieved 99.999% uptime of emails.

I've run into a problem with my Plesk install with Amazon Route 53. I have the latest extension installed (version 1.2 release 2) on Parallels Plesk v12.0.18_build1200140811.16 os_CentOS 7.
The extension has been working perfectly well for me for months. I was adding new domains to Plesk and discovered that as I was making changes to DNS records that a new zone file was created on Route 53 instead of updating the original one.
I did notice that this started happening when I surpassed the 100 domain limit and seems to only happen on domains created at #101 and on. (in other words, I can edit a domain that was created before I got to domain #100 [ie domain #1] and it does not create a duplicate zone file).
I turned on debug mode for plesk and am seeing the json calls with the correct commands coming through.
Redacted sample of an update of Domain #104
[2015-06-10 16:42:43] INFO [panel] The domain alias <b>mydomain.test</b> was created.
[2015-06-10 16:42:43] DEBUG [util_exec] [5578bd6355bc3] Starting: dnsmng /usr/local/psa/admin/bin/dnsmng '--update' 'mydomain.test'
[2015-06-10 16:42:43] DEBUG [util_exec] [5578bd6355bc3] Finished in 0.06322s, Result: TRUE
[Code] .....
So from what I can see the domain +100 is re-creating the domain whereas domain 1 is not - it's just updating it, even though both json commands show the update statement coming through.

how to make it so if the server that hosts my website receives too much traffic it will go to a mirrored copy of my website on another server? I want to make sure that it doesn't go down in the event of a big boost in visitors.

I need some expertise on how many servers we need for our site. Basically it is a flash interactive game where a heavy user might download 60-75 megs in a one hour session. Our hope is that we get lots of users, say around 1000 users an hour. Our current server is a AMD 3800plus dual core with 1 gig of ram. It is hosted through Aplus. I am just the programmer for the project and don't know anything in regards to servers, but my client wants to know if one server will be enough to handle the load of 1000 users an hour. Or should we run on multiple servers, etc.

Not sure where this belonged so put it in web hosting as it could cover dedicated, colo or shared.
In a couple of months I am going to be launching a new e-commerce website for the company I work for, so it is absolutely vital that the website never goes offline, otherwise I will be in deep ****.
It will be hosted on a server that has been built to be very redundant; 2x Hotswappable Redundant PSU, 4x Hotswappable HDDs (RAID 6), Redundant NIC.
Sods law though to achieve this redundancy it will need to be on a colocated server, so if there is a major problem like the motherboard dying, then I will have to get down to the DC (3 hours away) and replace the entire server. Which wouldn't be practical as we would need a replacement server, all setup and ready to go, to do that.
Also, if there is a problem with the data centre itself, then we would be stuck until it is resolved. I have hosted sites with data centres in the past that experienced power or network problems which sent the sites down and it was totally out of our control to either prevent the downtime or restore the sites.
So to increase redundancy, and minimise downtime, I was thinking of load balancing between two servers. But then I assume they would both have to be hosted in the same data centre.
I was also thinking of having the site hosted on the server, but having some shared hosting (or a cheap dedi) ready to go just to fall back on if the server goes down. That way I can forward requests to the shared hosting as a temporary measure whilst the main server is restored. But the problem with that is I would probably need to get another SSL certificate. I would need to get the payment gateway provider (protx) to change the settings for the IP of the shared hosting, which knowing them will take 72 hours to process.
Budget really isn't an issue here if it can be justified, just looking for some ideas at this stage. There is no way this site can be down for a second longer than it needs to be.

I have a server with debian 3.1 sarge and 2.6.19-grsec kernel.
Sometimes is happend that I cannot reach my server for a few days in any way (cant ssh to it, connect to vnc, connect to psybnc which run from it etc..)
It says connection timed out, but when I try to connect to my server from another machine, its ok, I can reach vnc,ssh,psybnc and so on..
and If I use that other machine to connect to my server regularly, this cant reach my server thing happens again as at my computer.

I wouldn't trust HostChum.com to host anything. Today I awoke to my server being down. No notice of anything no email no nothing of anything planned. So I goto their site to check the situation and wow their site is a parked page from godaddy so that doesn't get me anywhere. But I did write their phone number down just in case. So after many calls with no answer I left a message and phone number each time. No calls, no emails, no nothing.
Just gone into thin air, all my hard work of building sites and they just rip it out. I had a day of downtime just a week ago when the switched datacenters. Now they just shut everything down with not a word.
This has to be the worst treatment by a company ever, so I wonder if I will ever get to get the files from my server. What jerks save your money and never use this company.

My internet connection is up and running, I can visit any site except for www.hostingdiscussion.com
After I notified my hosting provider - they said they can see the site just fine. However, how come it would just suddenly go off like that for me?
Please let me know if the site is up for you or not. I am located in Montreal, so if any of you are here using Videotron as your Internet service provider,

I have two domains as virtual hosts on same IP address.
I am getting certificate error for the second domain when I try to check email (using MS Outlook). I can't permanently "accept" certificate, it complains again and again. Certuficate I created and self signed for imap.domain1.com, but the second email server is imap.domain2.com, so it complains.
How do I set separate email certificates for two domains? Is it possible at all?

Depending on where u are at on my site (documents pages, training, main root, etc.) will depend on which type of background, footer, header and the like you'll get. Now I was thinking. Is there a way to have multiple error messages for more then one page depending on where you are at on a site? Right now it's intranet site and a modded snitz forum. What is the code and were does it go and in which apache conf file(s) does it go in?

If I type google.com in my address bar, it forwards me to www.google.com. This is not happening for my website right now. I think its a good idea to do this, since then search engines will have only 1 main URL for the website to index.
My question is:
How do I implement this? I think this may involve mucking with CNAME settings...

I have a domain(ex. mydomain.com) hosted on a shared windows server, I also have a dedicated Linux server with a different company.
What I would like to do is have the mail be handled by the Dedicated Linux Server(cPanel/WHM), while the site is running on the shared windows server.
I understand I would need to change the MX Records for the domain on the Windows Server to point to the dedicated server's mail server IP Address (mail.SERVER IP ADDRESS.com ?), but do I also have to create an account on the linux server to handle the mail (example forwarders/auto responders).
If that is the case, how do I tell it to take care of all the mail coming for the domain mydomain.com?
