I will bring the new database server live this Saturday night, probably around 1am EST (so really very early Sunday morning.)
In addition to the new hardware, I'm upgrading MySQL itself from 4.1 to 5.0.
(If enough people are interested, I'll schedule a further upgrade to 5.1 later on...)
There are some minor backward incompatibilities between 4.1 and 5.0 ... I don't expect these to affect anyone here, but if you're using a lot of hand-coded SQL, you might want to look over the list of changes between 4.1 and 5.0
