Numerous Twitter users are reporting that access to Twitter and Facebook has once again been blocked in mainland China. This latest blockade comes one month after China has blocked access to these two sites, together with other major social networks and search engines.

According to ComputerWorld, Twitter has already been inaccessible in the last couple of days; Web2Asia now reports that since 8pm Chinese time Facebook has also been blocked. This has been confirmed by users on Twitter, some of which link the latest blockade to Uighur protests in Xinjiang, which had left over 150 people killed and over 1,000 wounded.

This latest attempt at censorship comes as no surprise as the Chinese government has sought to tighten its control over the Internet in the last couple of months. Unfortunately, the mechanisms of censorship seem to react faster and work better each time they're employed.
