Mail problem this morning (resolved)

Posted March 12th, 2008 in System Status. Tags: , .

Between 5:58 and 6:26 AM Pacific time today (March 12), a network problem on one of our mail servers prevented some customers from being able to read and send e-mail.

The issue has been resolved and everything is working normally. Although incoming mail was delayed, no mail was lost. Web site service was not affected.

The cause of the problem was that a debugging tool used by one of our technicians (“tcpdump”), when used with certain options, can apparently cause network interface failures. This was not an issue we were previously aware of. We will avoid using the tool in that manner in the future, so the problem should not recur.

We regret the problem and sincerely apologize to our customers who were affected by this issue.
