Brief power interruption for some servers (resolved)
This morning at 12:11 AM (Pacific time), one of the cabinets at our data center tripped a circuit breaker, causing all of the servers in that cabinet to lose power. Power was restored at 12:18 AM.
Customer Web sites and e-mail on the bender, calculon, lrrr, and zapp Web servers were unavailable during this 7 minute period. The ability to send and receive e-mail was also interrupted (no mail was lost, of course).
We are investigating the root cause of this problem to prevent it from happening again.
