The attacks are coming from gptdown. I just received an email from someone claiming to be the admin there that stated they have stopped the attacks.
Still not able to connect to pool1.us.multipool.us .
I've been connected to the eu one for a good 30 mins, but I can verify after removing the eu.multipool as my first pool that cgminer is still having issues connecting to the us counterpart (east).
I am also on the EU one, seems to be working good. Dare I say better then before with my 2 cards. lol
