^ Yep, that topic covers the full story pretty well.
If that's TL;DR, the short story is, all admins that actually had server access on the old site went AWOL, we were suffering more and more frequent (and large-scale) spambot attacks, and if the site were to go down, there'd be nothing we could do about it except wait and hope it came back up - which it did every time at that point, although since then it's gone down permanently (although it's unclear whether it's just a failure that never resolved, or if - more likely - the old admin noticed and took it down; the only reason I have my doubts is that, since the old site still seems to connect to some kind of server, if it was intentional then surely a link to the new site would've been placed there).
