There’s no internet censorship in China. A Chinese official, at a United Nations internet summit in Athens, explained:
I don’t think we should be using different standards to judge China. In China, we don’t have software blocking Internet sites. Sometimes we have trouble accessing them. But that’s a different problem. I know that some colleagues listen to the BBC in their offices from the Webcast. And I’ve heard people say that the BBC is not available in China or that it’s blocked. I’m sure I don’t know why people say this kind of thing. We do not have restrictions at all.
So this is, I guess, a mirage. And that study by researchers at Harvard Law School that found 19,032 Web sites that were inaccessible inside China? All caused, apparently, by temporary server failures.
