i think so. not blocked the last time i went in '02. i went on at a hotel if that matters any. havent tried local internet cafes, i suspect they probably arent blocked either. in fact, i dont recall being blocked from any sites i normally visit at all in china. including several forums, cnn, msnbc, nba, and some other, smaller sites.
went on in shanghai, beijing, xi'an, guilin, and hong kong. all seemed fine. didnt exactly like using some of the chinese windows though, i couldnt read it. lol.
