The Russian government maintains a growing list of websites banned within its borders. It claims this is to protect citizens from “extremist” content but is more truthfully used as a means to remove politically sensitive information.
Two popular services that are banned in Russia to this day include LinkedIn and ProtonMail. LinkedIn was banned in 2016 for not housing data about Russian citizens on Russia-based servers. ProtonMail was banned for not giving the Russian government access to its users’ data (as it’s a highly encrypted email service).
There are hundreds of other websites that, while not completely banned, are still heavily regulated. Amazon Web Services, Google, and Twitter are among the top sites restricted in Russia.
