Well, that was more trouble than it should have been. I upgraded an internal blog server from VW 7.4.1 to VW 7.6 earlier today, and after a few API issues got resolved, it was pretty smooth. So I went ahead and started the upgrade of the server here - which went a bit less smoothly. There was an outage of about an hour as I fiddled around trying to figure out the problem (not helped by watching the updated "Andromeda Strain" out of the other eye :) )
Anyway, things should be back to normal - but I won't be surprised to see a few small issues here and there either.
