As in our prior testing of Saudi Arabia <[1]>, there exists no publicly available master list of blocked sites. To assemble something approaching such a list, we have found ways to remotely test "twenty questions" style, asking about thousands of individual URLs, whether based upon a domain name or an IP address. We today released a report detailing the results of testing over the past eight months. We tested more than two hundred thousand web sites, and we found nearly twenty thousand to be inaccessible from China. Highlights include sites operated by world governments, non-governmental organizations, and educational institutions -- as well as sites with health, entertainment, and political content. Our report is available at <http://cyber.law.harvard.edu/filtering/china> We continue to operate a system for real-time testing of filtering in China: <http://cyber.law.harvard.edu/filtering/china/test> Ben Edelman Berkman Center for Internet & Society Harvard Law School <http://cyber.law.harvard.edu/> <[1]> Documentation of Internet Filtering in Saudi Arabia <http://cyber.law.harvard.edu/filtering/saudiarabia> ------ End of Forwarded Message ------------------------------------- You are subscribed as interesting-people () lists elistx com To unsubscribe or update your address, click http://v2.listbox.com/member/?listname=ip Archives at: http://www.interesting-people.org/archives/interesting-people/
