I have a VPS running Debian which has been fine for a while with no major changes that has suddenly stopped responding to the domain name associated with it, this is a registered .com domain, i can access the VPS via SSH and the webserver by using the IP address however not by the DNS any longer. I have done a whois on the .com and it is still valid etc and reported as being ok. This seems to be a DNS problem i should probably be looking at the domain name provider to solve, however i wonder if you guys have any other thoughts. Checking the logs on the server i can see nothing that should have caused this problem but to be honest i haven't ever had to deal with something like this. Thanks Andrew.
