"World of Warcraft servers taken down for maintenance and client patch 3.1.0 rollout. Outage clocked at more than 16 hours. National productivity increases by 10%."
It seems as though Blizzard's methodology for maintaining their World of Warcraft servers is to take them offline early Tuesday morning (often around 1:00am or 2:00am Pacific time) and to keep them offline until between 9:00am and 11:00am. During the client patch 3.1.0 rollout they took the servers offline at 1:00am and, at the time of this writing, don't have them back online yet. Instead there is a message on the client login screen indicating that "there were problems found in testing" and "we'll try to have the realms back online in the next two-to-three hours."
A small reminder to myself that a default installation of CentOS 5.3 does not, by default, include the Compat packages. The effect this has on Web Server is an installation that appears to have succeeded (bits are laid down on disk), but is completely unconfigured (no default instance or Admin instance are created). Re-running the installation and actually reading the screens shows an error:
