Firing one of the first shots in the net neutrality war, AT&T has blocked 4chans /b/ image board. AT&T subscribers are unable to connect to /b/ and /r9k/ (both of which are hosted on img.4chan.org). However, subscribers can get on any of the so-called «worksafe» boards that 4chan.org offers.
The problem seems to be present only for wired connections only (AT&T Mobility customers are not affected). The problem is not caused by an DNS-error, as traceroutes indicates that AT&T is dropping img.4chan.org requests in the AT&T network.
Slashdot, Digg & Reddit are now running stories that are rapidly being upvoted about the topic.

As citizens of a free internet, what do we think about this kind of censorship?
UPDATED 1: Confirmation comes from several Reddit users that the website has indeed been blocked in a number of areas in the US and that it is not a technical issue.
UPDATED 2: A mere 5 hours after the problems were first reported on Reddit, sources on /b/ say that members of Anonymous has already started planning retaliation towards AT&T amongst other things posting personal information about AT&T executives. One might quietly wonder if the AT&T megacorp. knows whats it up against with 4chan often being referred to as The Internet Hate Machine.
UPDATED 3: It turns out 15.5% of all US internet users use AT&T DSL, so this is quite a big problem. It will severly affect 4chan, both in regards of traffic and advertising volumes.
UPDATED 4: moot, the founder of 4chan, officially acknowledges the ban calling for disconcerned users to «call or write customer support and corporate immediately»: http://status.4chan.org Somehow, I get a feeling theyre gonna do a lot more than that, moot.
UPDATED 5: From rumors on /b/, it seems 4chans first retaliatory strike will be towards Randall Stephenson, CEO of AT&T. The Consumerist has more. There are also murmurs about the AT&T block being put into place because of supposed mass DDoS-attacks to and from img.4chan.org, but so far there has been no official, verifiable response from AT&T.
UPDATED 6: 4chans current gameplan evolving over at Encyclopedia Dramatica (Great stuff!). Also, from reports gathered on Reddit, it seems this block allegedly is because of massive DDoS-attacks against img.4chan.org. The reports doesnt say anything about why AT&T would block 15.5% of all US internet users from using a specific website without any warning, though.
