I have no idea why, and no-one who administers the machine is currently available. CLARIFICATION: If this saounds at all like I'm bitching about the folks who administer the machine hosting my domains, I want you to pay close attention to the following:
THE OWNERS, OPERATORS, AND HOSTS OF MY DOMAINS ROCK MY FACE OFF! YAY, THEM!
I say this not because my domains are back up, but because they are. This post was just an attempt to inform those who need to contact me that my mail was down, in case this was a longer-term outage, as happened once before, with no notification given to said Owners/Operators. They all rock old-school and hard-core and like that.
