Wikipedia in all languages is blocked in China
According to The Tor Project’s Open Observatory of Network Interference (OONI) which measures internet censorship around the world, all Wikipedia domains, irrespective of language edition, are totally blocked by the Chinese firewall since around April 5th. Its Chinese language site was initially banned in China in November 2016. The revelation came after the collection and analysis of data from China Telecom which is one of the largest Chinese network service providers. The ban followed and is believed to be related to, the authorities’ internet clean-up campaign, which was launched in late 2018, aimed at removing low-brow as well as harmful content from domestic cyber space.
