You'd think 22 million would at least buy a half decent site or at least have a more motivated staff! 
There is also the trust issue. One just can't hire anyone to work on a cladestine website, now can one? I didn't think that a DDOS attack was possible against a hidden service, or is all of Tor under assault?
Possibly a mixture of both...
There is a brief rise in the 50kb transfer measure but nothing out of the ordinary. I can't tell.
