Web services on jmac.org are hosed. I have a plan for fixing it, which I will start immediately and then continue as time permits; I'm in the midst of some time-sensitive Appleseed work that is of greater priority. I will post again with further status updates, as they come along. Things should be permanently better before next weekend.
Part of my plan involves migrating hosts once again, this time moving from tektonic.net to linode.com. Stating here that I am very impressed with Linode's service, which Planbeast now uses, and disappointed with Tektonic's. The latter was OK when I started using it last year, but either it's gone downhill fast or I was just lucky for a while. I have lately found its service unreliable, its online diagnostic tools faulty, and its customer service quite lacking. Bummer.
