Uh, hm. My hosting company seems to have had some sort of catastrophic event occur to the server that hosts this page. I'm pretty sure I have a reasonably recent backup of the code that would generate this page, but I'm going to hold off restoring it until I can find out what happened.
(I'm also in the middle of a move and about to start a new job, so I may not get to this right away.)
Apologies for any inconvenience.
