You should try Ben Edelman's empirical stuff on Internet filtering in
China:

I think this is the most reliable method going, though I have heard a
counter-argument that the poor overall quality of Internet infrastructure
in China gives Edelman false positives.  (That is, the sites are
unreachable, but not blocked.)
