This site (and every other site I have) was down from ~2 or 3am until about 9am today, the 24th. I don't know what caused it, exactly, but Dreamhost (my hosting provider) was quite courteous and responsive and resolved things just under 1.5 hours after I contacted them.
At least things appear to be running now... if they go down again, I'll get on the phone and see what was really going on.
