DT just sent out a tweet on this:

and before that, an announcement came from the _defcon_ feed:

If you are a user of twitter, you might consider following these two.

Forum updates appear on:

(I try to keep the forums updates down to just forum updates, and don't include personal information. Things like creation of forums, activation of contests, maintenance windows, known loss of service, etc. are all posted as tweets. It has been useful in the past to let people know that a loss of service was a known problem, and reported, when there were problems with an ISP used by Defcon.)
