Russian government wants to keep most Internet traffic inside the country, fearing it foreign governments might wiretap sensitive communications. 60% of Russia’s Internet traffic is re-routed through servers located in other countries. Russian state-owned telecommunications provider Rostelecom says this plan is doable and will not incur heavy costs on local ISPs. The plan also implies that major Internet services will use Russian CDNs to store local versions of their websites. In 2015, Russia has passed a law that forces foreign companies to keep data on Russian citizens on servers.
