Zapp server temporarily unavailable (resolved)

The “zapp” Web server was unavailable between 3:43 and 3.53 AM Pacific time this morning, April 4. This resulted in an interruption of service for Web sites on that server. (Some e-mail activity was delayed, but no e-mail was lost.)

We sincerely apologize for this problem. We consider this type of failure to be unacceptable, and are looking into the cause of the problem so that we can take the appropriate steps to prevent it from happening again.
