As most of you have figured out by now, we are under DDoS attack and have been for the past week or so. We've been trying to avoid calling it out, as often that empowers the attackers with the limelight.
We don't know who it is or why. They seem to be targeting multiple trackers but are going harder against some trackers more than others.
The scale and type makes it difficult to mitigate. Those that can access the site have better peering than most of the attacking machines and can get through. We’ve taken some measures to try to make the site somewhat usable, and we have some options to try to mitigate the attack further.
We will provide updates to this issue going forward, and let you know if there is anything further to note.
