Poloniex has been crashing a lot in the last bit due to DDOS attack.
Yah, I can't log in either. Could they be blocking my ip range?
Not likely that you are blocked. Seems to be working now, but it's been up and down for the last several hours.
They should use something more p2p-like for their hosting,
ZeroNet for example. Of course it is not matured enough yet, but it is potentially more resilient to DDOS threat.
