Twitter users in China began reporting outages in service Tuesday afternoon, many taking to blogs and news outlets to voice their outrage. Users also reported having trouble accessing the site through third party clients, such as TweetDeck and Twhirl.
The Chinese government regularly tightens access controls to social networking websites when approaching politically sensitive dates. Google's YouTube has been blocked in the country for a number of months, with access granted intermittently, usually for government meetings.
Hours after the blocks were reported, 'China Blocks Twitter', 'Twitterblock' and 'FuckGFW' (great fire wall) began rising in Twitter's trending topics list.
