If you're wondering what happened, here's what my host had to say about it:
Overall I was happy with how the guys (<a href="http://www.4webspace.com">4webspace</a>) handled it Too bad there wasn't some kind of backup system in place that could be used to replace all my data automatically But tech support as always was prompt and quite helpful.(Dave:) Your 4webspace raq server crashed earlier this afternoon. We attempted a number of different fixes (swapping memory, replacing a dead case fan, swapping the drive to entirely new hardware), but were unable to get it to function again. Further investigation showed that the boot sector of your hard drive had corrupted, and the drive will no longer boot, nor are we able to image it to an undamaged drive. We are, however, able to get the drive to detect when mounted as a slave in another system ...
(Rob:) It looks like the hard drive just cratered basically. There is a brand new one in there now so it shouldn't happen again for at least a few years anyway. The server will no longer boot from the old drive, but it looks the majority of data on it is still good.
Edit: Okay all user website accounts on dosgames.com are now back up too
