We're doing a scheduled upgrade of Identi.ca to the status.net platform tonight, Wed 24 June, at 11:59PM EDT. (Just before midnight). This is short notice, but after our miss last week we really wanted to be ready before going forward.
We hope to be offline for <2 hours, with a strong probability of less that 1 hour. We'll keep this blog post (on a separate server) updated as the night goes on.
Update 9:06 PM: we're going offline now.
Update 9:59 PM: moved databases, moved XMPP server.
