Server Fault is a question and answer site for system and network administrators. It's 100% free, no registration required.

I need some help on why one of my sites constantly goes offline and back online all day like 30 times a day!. The downtime varies from 10 Minutes to 55 Minutes and its really affecting me. I have other sites running just fine on the same server, same Plesk, same IIS. Here are some details:

  • The Domain is registered at GoDaddy.com (in case you need me to look up something
  • Server is Windows 2008 R2
  • Plesk is the Control Panel 9.x
  • Running IIS 7

I was told Plesk has its own DNS so the IIS one is Off so leave it off. Not sure if this is true but since all my other sites run just fine, this is probably true.

I would appreciate the help if someone can tell me what I need to fix/add/change to this domain!

The domain outlooksync.com is registered with two nameservers, NS1.MSWINDOWSHOST.COM and NS2.MSWINDOWSHOST.COM. These are also the nameservers for mswindowshost.com, which requires registrar glue. But no registrar glue has been provided. So this happens:

1) Client wants to find www.outlooksync.com.

2) It has to ask ns1.mswindowshost.com.

3) So it looks up the nameserver for mswindowshost.com and gets ns1.mswindowshost.com.

4) Infinite loop. Oops.

Someone has to fix the registration for mswindowshost.com (by adding glue or changing the nameservers) or someone has to change the nameservers for outlooksync.com.

Update: Right now, the registrar says this:

Domain servers in listed order:

But the nameservers say this:

  mswindowshost.com       nameserver = ns.mswindowshost.com.

I miss the old days when WHOIS lookups returned the names and IP addresses of authoritative name servers. –  James Sneeringer Jan 13 '12 at 4:48
I changed the IP of outlooksync.com to a different IP address. I have let it propogate for 3 days+ and I still have constant, constant downtime for various minutes all day. now I do want to state I did have a 100% update for 18 hours just yesterday and I thought the issue was solved. but then it started going in and out again. Now what else could be wrong? Strangest thing is that the server also hosts alot of my domains(dedicated server) and they are all OK, except outlooksync.com. thanks David...in advance... –  DevCompany Jan 17 '12 at 4:41
You need to fix the actual problem. Read my answer. Nothing has been fixed, I just confirmed the problem is still exactly the same. You have a loop: outlooksync.com -> ns1/ns2.mswindowshost.com -> mswindowshost.com -> ns1/ns2.mswindowshost.com. The problem has nothing to do with the IP, it has to do with how a client's nameserver would find the IP addresses of the nameservers. –  David Schwartz Jan 17 '12 at 5:37
then the same settings are on www.brightslides.com so why does that have no issues? –  DevCompany Jan 17 '12 at 6:17
Actually, the problem is subtly different. The registrar thinks the nameservers for mswindowshost.com are ns1.mswindowshost.com and ns2.mswindowshost.com and the zone file says it's just ns.mswindowshost.com. –  David Schwartz Jan 17 '12 at 6:23

Then you need to contact your hosting provider to check what is the issue. Or you can find another hosting provider that have UPTIME Guarantee. You can check it at http://www.microsoft.com/web/Hosting/Home. Good luck

Its my own dedicated server that hosts a number of my other sites, which are all 100% uptime. Its only this domain. –  DevCompany Jan 17 '12 at 4:45
