web04 server restarted (resolved)

At 3:33 PM Pacific time September 12 2012, our “web04” server became unstable and needed to be restarted. This led to an 8 minute outage of Web sites and e-mail hosted on that server.

All services are now working normally, and other servers were not affected.

This isn’t normal or acceptable. We take server reliability seriously, and we’re investigating the underlying cause to avoid a recurrence of this problem.
