China is one of the country in the world always to "protect" the citizens by considering blocking many web sites in the world. Youtube is banned my China Authority because of there are some people uploaded video about Lhasa, Tibet protest demonstration. Lhasa is the main capital of Tibet. Meaning "holy place" in Tibetan language. The people of China who surf Youtube will experiencing 'This web site cannot be displayed'.
Well I am interested too to 'fing' out which pieces of land in the world block Youtube and i got a quite detailed result. You can click me here to see it.
