However, do a more "interesting" search, such as 天安门广场事件 (Tiananmen Square Incident), and no page is able to load. A standard error message is displayed instead (in this case "The connection was reset...")
Who knows if these same results will hold tomorrow but... this sure isn't an accident. China was clearly prepared in advance for Google's recent actions.
China's response is not limited to Google's sites in "Greater China" and appears to be an actual extension of its censorship.
The World Expo opens in Shanghai in just over 40 days. Will be interesting to see if the Google events and those related complicate China's desire to use the World Expo to present a positive image of China to the world (although projections seem to be that the vast majority of visitors will be Chinese).
Some additional points
The results from inside of China for Google's Hong Kong site also hold true for Google's sites in Spain & Israel (which should be noted have different domain name structures: www.google.es andwww.google.co.il). China is being rather thorough. When it comes to Google, China is breaking the mold of letting more eager Chinese internet users find holes in the wall.
While 天安门广场事件 (Tiananmen Square Incident) is "blocked", 天安门广场 (Tiananmen Square) is not.
天安门广场事件 is not a blocked search on Microsoft Bing in China nor Baidu. However, the search results do appear to be mostly missing any links, images, etc. that one would expect to be censored."
