Until Tuesday, Web users who turned to search engines like Google and typed in the word Shanwei, the city with jurisdiction over the village where the demonstration was put down, would find nothing about the protests against power plant construction there, or about the crackdown. Users who continued to search found their browsers freezing. By Tuesday, links to foreign news sources appeared but were invariably inoperative.

But controls like these have spurred a lively commentary among China's fast-growing blogging community. "The domestic news blocking system is really interesting," wrote one blogger. "I heard something happened in Shanwei and wanted to find out whether it was true or just the invention of a few people. So I started searching with Baidu, and Baidu went out of service at once. I could open their site, but couldn't do any searches." Baidu is one of the country's leading search engines.

If you remove the "hl=zh-CN" from that Google news search above you get VERY different results. There are some relevent links in the Chineese web search results right now, but the results seem odd given the amount of press coverage. This news search has relevent information, but its mostly coming from a handful of protesty news sources (peacehall & epoch times), same ones that show up in the google search, and not mainstream media. Its possible that these are approved dissenters. (Although VOA also shows up.) More totally unreliable information here. Stratfor has coverage here.
