Are they going crazy? Before they would warn and order the webmasters to delete "harmful" information from their websites, sometimes they just blocked the website. But now thousand of websites would be blocked if they are so unlucky to be hosted by the same IDC company with a "harmful" website.
Yes, in the last month, most of the interactive website(including forum, guestbook, blog) in China were blocked by the Chinese authorities. Some believe this is because of the 17th National Congress of the Communist Party of China opening, the Chinese authorities want a social stability.
Chinese authorities often blocks an entire Web site, even if only parts of the site contain sensitive information. Just in the last month, more than thousand of dedicated server in HeNan TeleCom room and ShanTou TeleCom room were closed forcibly. thousand of sites were blocked included those on health, education, news, entertainment, religion. Also they use the Greate FireWall to blocks some great website like FeedBurner and Flickr.
This month, the Chinese authorities will finish their jobs, closing the rest of "illegal website". So when the 17th National Congress of the Communist Party of China is opening, the Chinese cyberspace will become a very harmonious and stable.
Not a country renowned for freedom of speech, China has nevertheless outdone itself with more internet censorship that would make them proud.
