AT&T blocks 4chan.

It's over.

AT&T DECLARES A CEASEFIRE

"Just got a call back from AT&T - seems the reason for the block isn't CP. It's because the site is a constant target of DDOS attacks that were routed through AT&T servers. AT&T blocked it because their bandwidth was spiraling out of control."

It seems the problem WAS Anontalk & co after all. AT&T detected the constant DDOSing of 4chan's servers, the attacks were coming from AT&T lines. So they shut off those lines to stop the DDOS against 4chan and stop their bandwidth rape.
