Some reports are suggesting that Google.cn has begun to be blocked by the Chinese authorities, after Google's decision to no longer filter results – although other sources suggest that the action has not yet been rolled out across the nation.
"Looks like the ax has fallen: Google.cn now blocked for me (China Telecom in Beijing)," tweeted Kaiser Kuo.
However, other tweets from China-based Twitter accounts suggest that it is not yet widespread.
Reuters Beijing Bureau Chief, Gady Epstein has tweeted "Not blocked for me yet (Unicom)" soon afterwards.
And Greg Anderson, @GE_Anderson, tweeted "Google.cn still accessible in Shanghai."
