Wouldnt suprise me, I've been working out of china for the last few months and the amount of censorship is crazy. Right now i cannot acces that site you just posted, not sure if its more likely blocked.
Some other things I've noticed:
Google video is band.
Wickepedia is band.
Sometimes I search google with one of the keywords being "china" and google will stop working for the rest of the day ;P
I think their watching me right now... so i'll keep this short...
