All my subdomains stopped working!

Posted on 2012-04-02
Last Modified: 2012-04-03

I had about 10 subdomains. Last Friday everything was fine, on Monday they cannot be reached.

-The Apache config files look fine to me
-the original main domain works fine only the sub domains not
-If I want to reach a sub domain it is even not logged in the access.log, neither in error.log
-I even cannot ping the sub domains

What can I do?

Thank you

Check your DNS server to make sure the records still point to where they should be....

Please provide atleast one subdomain which is not working? Also check the DNS settings on Main domain's DNS server.

Is it kind of buddypress where users can create blog using subdomain? if yes than check for DNS Wild Card entry.

No, only I can create subdomains. They are for internal use only.

Ok but how you create a subdomain? if you want to get Subdomain working there should be something in DNS which is missing from your setup due to which the subdomains are not working.

In order to resolve a URL on the internet ( or or there needs to be a proper DNS record for each of them. There needs to be a DNS record for as well as for and for and or else no one will be able to resolve the names. Your other option is a wildcard record * or * that point to the correct server. Without DNS records you can only access the sites via IP address since you have no way of figuring out where that name exists.

The Dns server owner deleted the Wild Card setting for my domain and that caused the problem. I needed to set up manually the sub domains.
