Russia will examine its interior RuNet system to see whether the nation can work without the global internet, the Russian government proclaimed Monday. The tests will activate after Nov. 1, recur at least annually, and possibly more often. It’s the most advanced move in a range of technical and policy stages intended to allow the Russian government to scratch its citizens off from the rest of the world.

“On Monday, the government permitted the provision on conducting exercises to ensure the stable, safe, and holistic running of the Internet and public communications networks in the Russian Federation,” records an article in D-Russia. (The original article is in Russian. We confirmed a translation with the help of a native Russian speaker.) “The movements are held at the federal (in the territory of the Russian Federation) and regional (in the territory of one or more component entities of the Russian Federation) levels.”

The word “holistic” displays that the exercises follow April’s passage of the sovereign internet law that will need all internet traffic in Russia to pass through official chokepoints, permitting the government to shut down outside access, stop websites that they don’t like, and monitor traffic.

In 2016, Russia released the Closed Data Transfer Segment: basically, a big military intranet for classified data, comparable to the Pentagon’s Joint Worldwide Intelligence Communications System. The following year, Russia declared that it intends to build its own domain name directory, which would permit it to re-route traffic intended for one website to another.
