Sucks, but makes sense.
I'm surprised they even attempted to use that domain. The instance still exists and will need to be routed through a new domain. Which, again sucks, because any reference links will be broken now... which... again... has me wondering why they even went with that domain in the first place. Albeit, it was a clever use of a top level. I wonder how many others are doing the same.
