Earlier today (about 13 hours ago) we noticed our email wasn't working and sites weren't coming up. After further investigation and a support ticket that's been going nowhere fast, it appears as if it's a problem with our dns server (or perhaps something related to it's port?).

It was working fine and stopped working out of the blue. Nothing was changed or modified on our end. The service is up and running, I've tried restarting it (appears to restart fine), but none of our domain names resolve.

Any help would be much appreciated as our customers will not be happy come morning.. I've been monitoring my ticket since 3:00 this afternoon (with the exception of taking a little nap around 1 for 3 hours) so I'm quite exhausted.

Thanks

Can you telnet to that port or run any kind of dns lookup against the server? Also have you checked the logs?

Yes, I can telnet to that port and nothing weird appears in the logs.. however, if I do a dns lookup (and dnsstuff, for example) it times out.

UPDATE: Looks like it's fixed. Somehow, my IPs became unbound from my network card. I sure didn't do this, I'm wondering how this would have happened...

Maybe a hamster modified your network file??? O.o


or maybe it was corrupt?
