It isn't surprising to us that China is censoring something. A quick scroll through the Mashable story archives will find more instances of censorship than you can shake a stick at. Therefore it only comes as a mild shock that the country has gone back on it's word to bring down the great firewall of China.
Word comes from Kenneth Tan at the Shanghaiist that "[t]wo days after Danwei reported the unblocking of Blogspot," China has decided to block CNN. He reports that several of his readers, one at China Netcom in particular, have been getting connection reset, a tell-tale sign of China's decision to block a site.
Kenneth theorizes that it's a result of the recent saga of Jack Cafferty, and his perceived biased reporting on the part of CNN. In fact, the reporting isn't particularly biased, but the commentary definitely has an anti-China bent to it. In a press conference on Tuesday, Cafferty more or less besmirched the entire country, saying " I think they're basically the same bunch of goons and thugs they've been for the last 50 years."
CNN later issued a formal apology, but apparently, China is still not amused.
