-- Censorship or maintenance? That's the question after China's two biggest web portals shut down, media in the region reported Tuesday.
Agence France-Presse and South China Morning Post both reported the search engines of Sina.com and Sohu.com have been shut since noon Monday, launching speculation that the sites may toughen their censorship methods.
The AFP wire service said some spokespeople at the companies claimed they were only going through upgrades. But the Post, a Hong Kong-based newspaper, said the portals have been given time "to rectify their mistakes" after censorship tests showed they failed to filter certain keywords. --
