On 2nd of June, a number of overseas websites including twitter, flickr and youtube have been blocked. Today, on 3rd of June, a large number of local websites, including Fanfou (Chinese version of twitter) and VeryCD (user generated resource sharing website), have put up system maintenance notices stating that the websites would be inaccessible until June 6.
According to some twitter reports, some websites decided to take a few days off because of the pressure from propaganda department. Website administrators were asked to tighten their self-censorship, if any post carry key term such as “democracy” tomorrow, the websites would be forced to close down.
