Identi.ca is currently down; I just got off an airplane. We had a flood of new users and posters over the last 24 hours, and the extra traffic seems to have sunk our database server.
I'm trying to revive the server (it's currently re-starting), but I might take the opportunity to move to our new data centre. If we're down, maybe it's time to do the move. Watch this space for details.
Update 14:50 PM PST: I can't seem to revive the main database server, so I'm copying data to another server in the same data centre to see if it wants to wake up.
