Hello,
We are having an issue where our network connection is dropping on our server. Everything was working for about a month without issues then suddenly we expereinced a network outage.
Here is what I found in our logs. Rebooting the machine was the only way to have everything come up.

We have the same exact server, running the same exact debian version for over a year with no issues. Any suggestions?
Scheduled Maintenance: We are aware of an issue with Google, AOL, and Yahoo services as email providers which are blocking new registrations. We are trying to fix the issue and we have several internal and external support tickets in process to resolve the issue. Please see: viewtopic.php?t=158230
