A question-and-answer page on Google's Hong Kong's website became inaccessible to some mainland Chinese users this morning. The Google page (www.google.com.hk/wenda) provides Chinese-speaking Internet users with a forum to ask questions of any description.

Some visitors apparently asked about the June 4, 1989, crackdown on pro-democracy demonstrations around Beijing's Tiananmen Square. One questioner asked when China would have its next Tiananmen uprising, with answers including "soon; the Communist Party will collapse". Others made nasty comments about former leader Mao Zedong which do not go down very well with the Chinese government.

Now multiple users in China reported getting error messages when they tried to access the page.  Google told Reuters that there was nothing technically wrong with the site.
