Okay, We're Back
All right, here's the debrief.
As I mentioned previously, we moved to the Dreamhost PS virtual private server thing. Unfortunately, we were getting clobbered by something somewhere that was keeping us from even getting to the site via the Web. FTP was fine, though.
Now, as to what actually happened, I have no idea. The two theories offered up by Dreamhost technical support were that we were getting hit by some bots that we had previously been shielded from on the shared hosting and/or some bot was creating some sort of endless loop that was making our PHP processes inflate to bursting.
