I just realized the site was down again. Oh noes! etc. Then I looked at the calendar: I do believe that today is when I had set my domain name to be transferred to another reseller, namely my hosting company. They had warned me it might take the site down for a bit. I sure hope that's the case. In any case I fired off another help desk ticket, and am bracing myself.
Update: nope -- it was a server monitoring tool failure, so they didn't realize the site had gone off line until I (or maybe someone else) notified them. Vigilance pays off! Anyway, they are taking the lazy tool down to the hosting company basement and giving it a good spanking.
