Almost everything is back up. Apologies for the super-extended outage. I suppose it's bound to happen every few years, but we'll get to work on making sure this particular failure won't happen again.
Roberts been nudging the MySQL databases and no data should be lost. (A few databases did disappear, but we should be able to find a backup or otherwise restore it from exported data for all of them). Cross your fingers for us!
We're still working on making sure all the RT data is in good shape before putting it online, but it should be back one of the next few days.
Let us know at ask@ and robert@ if you see anything strange in the next few days. (Or when RT is back then at webmaster@ ...)
Thank you for your patience!
