Russia has ramped up the balkanization of its technology and infrastructure over the past few months. The government's "sovereign internet" law -- which allows content to be blocked in an "emergency situation" -- took effect in November, and President Vladimir Putin recently signed a law that bans the sale of devices without pre-installed Russian apps. Today, Russia's Ministry of Communications announced that it has successfully tested a countrywide alternative to the internet, according to the BBC. How this network functions isn't clear, but the Ministry of Communications claims that users didn't notice any changes to their typical web use during the testing phase.
