Russia has increasingly regulated the internet through laws requiring data localization, anti-piracy legislation, and laws governing media outlets and censorship. The data localization law, effective September 2015, requires personal data of Russian citizens be stored on servers within Russia's borders, raising concerns about ease of government access to data and additional costs for foreign companies. While some see this as a reaction to mass surveillance by the US and a matter of sovereignty, others argue it undermines the global and resilient nature of the internet and creates barriers to competition through protectionism. The implications for internet governance and Russia's approach to internet development and regulation going forward remain to be seen.
