Not sure if this is the case for profinity.com, but if you keep hearing about a lot of web sites that went "down" on Dec 23/24, the reason is that Network Solutions ("the dot com people") decided that would be a good day to shut off the domains of all domains that had outstanding bills since October. Yeah, right before one of the biggest holiday weekends, good idea. Just another reason Network Solutions is a bunch of morons. A few prominent domains went down.

(I had somehow forgotten to pay the bill on my personal domain, and I got exactly one notice of it, in October, before it was shut off in the early morning of Dec 24). I paid it on-line on the 24th and it was back running in 24 hours, which I have to say is a model of efficiency, by their standards.
