Rob T Firefly writes "The International Herald Tribute reports that the lifting of China's Wikipedia ban earlier this week was short-lived. Wikipedia is once again inaccessible from behind the Great Firewall, along with all other Wikimedia projects. Additionally, the URL of Chinese Wikipedia is once again a banned search term. No reason has yet been given for any of it." From the article: "It wasn't immediately clear if Wikipedia was inaccessible due to technical glitches or because government censors had blocked the site again. The Foreign Ministry and Ministry of Information Industry did not immediately respond when contacted for comment Friday. Beijing blocked access to the English and Chinese versions of Wikipedia in October last year, apparently out of concern about entries touching on the country's sensitive spots -- Tibet, Taiwan and other topics."
