Little bit on DDoS attacks:
They're a bitch to defend against...but they're also a bitch to maintain. CoSo is particularly vulnerable right now due to both what I would call politics (as the bird site collapses) and the huge influx of new users (as the bird site collpases).
Depending on where Jester has defenses deployed, it may be an extremely short-lived inconvenience or a fairly short-lived inconvenience.
TLDR: give it time and all will be well.
