Medium, a U.S.-based online publishing platform, has been blocked in China, the company said, the latest service to be affected as Beijing exerts greater control over the Internet.
Medium, which allows users, including companies and media outlets, to post blogs that readers can annotate, has been inaccessible since at least early this week, according to Internet users in China and tests by Reuters using tools developed by anti-censorship watchdog GreatFire.org.
A representative of San Francisco-based Medium said in an email, "We are aware of the block and we don't have definitive knowledge why the block has occurred."
