This is fairly disturbing. It demonstrates to governments around the world that it's possible to censor the web for particular geographic regions. This is going to lead to demands for a lot more of the same from repressive regimes worldwide. I won't be surprised when this comes up at the UN, not for denunciation, but under demands for 'sovereignty' by some nations to protect their citizens from objectionable content. 'Objectionable' meaning whatever those in charge think it ought to mean.
Quite easy to circumvent.
Look at my nic. Tor, anyone?
