Site has been down for 2 days now. IRC Channel is still up, however, there is no site status updates in the channel topic.
Room chatter had the following quote: Quote from one of the staff of BitHQ:

I will tell you now. The site was not seized or taken down by any agency. And the site owner has said over the last few months that he was no longer willing to continue to support the site financially. We had been unable to find a replacement owner. And to be honest.... I believe this to be the final demise of BitHQ.

We can only wait and see!!
