Status says unresponsive? Is that the same as closed?

While it probably means something slightly different, it can point to the same thing. For instance, I think it just went down now, and for a few minutes I was seeing 'Unresponsive?' before it updated to 'Closed'
Now I'll be quiet and see if anyone who actually knows something responds. An unresponsive forum is only slightly more fun than an unresponsive game server. At least with an unresponsive forum you have the cathartic possibility of a good shout into the void.
