The main Wikimedia servers in Florida will be moving to larger rackspace today. Among other things, this will take the mailing lists and Bugzilla offline for some or all of the day; sorry for any inconvenience!
The #mediawiki IRC channel on irc.freenode.net will be alive and well during this time, though during some periods we may be a bit busy reinitializing servers.
