The other is that vhost1.itasca.net, aka mail.14850.com, seems to be even more catatonic today than on most Mondays. (It does a weekly backup that starts late Sunday nights and often lasts into the next day, occupying a lot of system resources, if I understand the explanation correctly.) It has spent most of the day refusing incoming mail; it should all trickle in later, but lots of it will be delayed and out of order. The good news is, that makes the frequent login failures less of a problem; there's no new mail waiting for me anyway. :-)
Apologies to anyone else who's using 14850.com mail, or anyone trying to reach me via e-mail or IM.
