Brief scheduled maintenance February 26 2013 (completed)

Between 11:00 PM and 11:59 PM Pacific time February 26, 2013, each of our servers will be restarted for a “kernel upgrade”. This will cause an approximately four minute interruption of service for each customer at some point during this hour.

During that four minute period, customers will not be able to use their Web sites or read e-mail. E-mail that arrives during this period will be queued and redelivered after the maintenance, not lost.

This maintenance and restart of all servers is necessary for security reasons. We apologize for the inconvenience this causes, together with the short notice (this issue is important enough that the patch should be applied as soon as it’s available, which is today).

Update 11:30 PM Pacific time: The maintenance was completed with less than 3 minutes downtime for all servers except web01, which took a few minutes longer because the Apache software on that server needed manually starting due to a technical problem that we have permanently resolved.
