Call off the raid.
"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.
*censored.2.0*'s over, go home now.
