We got hacked. The database is gone.
Seems it was through Postgres:
Unfortunately through what seems to have been a misunderstanding on my part
we don't have a current backup. Bob has offered a database dump from
February, and I am currently working on a bit of SOAP to use Google's API to
retrieve all their cached copies of the site. A fair bit of work is going to
be involved getting the site up and running again, and I can't promise it's
going to be ready very soon.
