Brief scheduled maintenance February 18, 2012 (completed)
On Saturday, February 18, 2012 between 10:00 and 11:00 PM Pacific time, we’ll be upgrading the Apache Web server software on each of our Web servers.
Most customers will not notice anything, but the upgrade will cause approximately 30 seconds of slow Web page loading at some point during that hour as we delay incoming connections at the network level.
This maintenance is necessary to apply security and reliability fixes released by the Apache developers. (We’ve been using the upgraded version on our Webmail servers for several days, so it’s well tested.)
Update: The maintenance was completed at 10:03 PM Pacific time.
