Censorship of Wikipedia
Widespread censorship of Wikipedia has occurred in countries including (but not limited to) China, Iran, Myanmar, Pakistan, Russia, Saudi Arabia, Syria, Tunisia, Turkey, Uzbekistan, and Venezuela. Some instances are examples of widespread internet censorship in general that includes Wikipedia content. Others are indicative of measures to prevent the viewing of specific content deemed offensive. The length of different blocks has varied from hours to years. When Wikipedia ran on the HTTP protocol, governments were able to block specific articles. However, in 2011 Wikipedia began running on both HTTP and HTTPS, and in 2015 switched over to solely HTTPS. Since then, the only censorship options have been to block the entire site for a particular language or prosecute editors, which has resulted in some countries dropping their bans and others expanding their bans to the entire site.
