Wikimedia censorship in mainland China

The outside world believes this is caused by the Chinese government's censorship and blocking of sensitive content in Wikimedia Foundation projects.

On the afternoon of May 19, 2015, Chinese Wikipedia became inaccessible in mainland China due to an HTTP connection reset and DNS contamination[10] of "zh.wikipedia.org".

Users can get around this by modifying the local host's file or changing the DNS server and accessing the encrypted version of Wikipedia (HTTPS).

[11] The block did not affect Wikimedia's other projects (except Chinese Wikinews, which DNS contaminated) and foreign language Wikipedia.

[citation needed] In December 2015, after Wikimedia switched to mandatory encryption throughout the site, rendering keyword filtering ineffective, all language versions of Wikipedia were briefly made inaccessible in mainland China via the blocking of its IP address.

On August 24, 2018, the Great Firewall adopted SNI detection to block Chinese, Japanese, and Uyghur Wikipedia domain names, which made it invalid to bypass the network blockade by modifying the host's file or changing the DNS.

[citation needed] Since April 23, 2019, the entire Wikipedia site (*.wikipedia.org) has been completely blocked in mainland China,[13][14][15] and its home page and all language versions cannot be accessed commonly.

In addition, the IPv4 addresses of the Wikimedia Foundation's media server upload.wikimedia.org in San Francisco and Ashburn (198.35.26.112 and 208.80.154.240) were stopped for an unspecified period.

Authorities said he used the wall-turning software "Blue Light" to search for information on Wikipedia and was visited by police to "check the water meter."

The official website of the Zhejiang Provincial Party Committee announced that from the first half of 2019 to October 2020, the man repeatedly used the "Blue Light" wall software to "illegally access Wikipedia to obtain information".

We are an encyclopedia.After Wikimedia was blocked for the third time in October 2005, Wales summarized the arguments he made in his speech at the World Summit on the Information Society in Tunis:[38] 1.

[39] Later, at the second World Internet Conference held by the Cyberspace Administration of China in Wuzhen, he said:[40] I believe as a result of this, the idea that any one government can control the flow of information of what people know in their territory will become completely antiquated and no longer possible.However, the interpreter at the meeting translated his words as "also, the government can do a good analysis of the communication between people in their respective fields.

"[41] On July 19, 2018, Wales attended the Asia-Pacific Economic Cooperation Digital Innovation Forum (APEC DIF) in Taiwan and introduced his new website, Wikitribune.

Jimmy Wales said in an interview with the media that he would continue communicating with the Chinese government to lift the block on Wikipedia in mainland China as soon as possible.
