There was a posts week or two ago from a person running a legit Tor service that was analyzing all of the attacks he received.
He said something seemed to be dos'ing the guard nodes, causing his service to automatically choose a new guard, in an attempt to get his service to connect to a guard node controlled by the adversary. He said in one case, they found his server's actual IP address and dos'd it.

Could that be what happened?
