BEIJING -- When access to Wikipedia, the online encyclopedia that anyone can edit, was disrupted across China last October, a lanky chemical engineer named Shi Zhao called his Internet service provider to complain. A technician confirmed what Shi already suspected: Someone in the government had ordered the site blocked again.Who and why were mysteries, Shi recalled, but the technician promised to pass his complaint on to higher authorities if he put it in writing.
"Wikipedia isn't a Web site for spreading reactionary speech or a pure political commentary site," Shi, 33, wrote a few days later. Yes, it contained entries on sensitive subjects such as Taiwan and the 1989 Tiananmen Square massacre, but users made sure its articles were objective, he said, and blocking it would only make it harder for people in China to delete "harmful" content.
Shi was hopeful the government would agree. When the site was blocked in 2004, he had submitted a similar letter, and access had been quickly restored. Since then, the Chinese-language edition of Wikipedia had grown, broadening its appeal not only as a reference tool but also as a forum where people across China and the Chinese diaspora could gather, share knowledge and discuss even the most divisive subjects.
But today, four months after Shi submitted his letter, Wikipedia remains blocked.
