Following last weekend’s deadly riots in its western region of Xinjiang, China’s central government has taken all the usual steps to block citizens from accessing foreign web services: aside from crippling Internet service in general, the authorities have blocked Twitter, removed unapproved references to the violence from search engines and has now apparently moved to bar its citizens from accessing Facebook from most parts of Mainland China just now. Two weeks ago, the government had already blocked just about every Google service, including communication tools like Gmail, Google Apps and Google Talk.

Web2Asia’s George Godula writes:

“As of today 8pm Chinese time Facebook seems not to be accessible from most parts of China Mainland anymore. On the China Telecom connection of our Shanghai office the service vanished at around 7:45pm. Friends in Hong Kong are reporting that they can still access the website.”

A quick test on WebsitePulse confirms the blocking of Twitter and YouTube (which have been restricted for a while) and now Facebook too, at least in some parts of the country.
