Can I ask that developers use LiveJournal - http://www.livejournal.com/community/wikitech/ - to keep people informed about problems on the Wikimedia servers and what's being tried to fix it. People are much happier about something being broken when they know why and what's being done about. We also need one central low-noise source for information, and I feel the LJ is probably the best bet for that.
Ta,
