From what I can read in that article, the law will simply mandate that Roskomnadzor gets to control the internet access points, and it's also hinted that services will be required to host their data in Russia, to some extent. That would give them the ability to shut down most of the Internet traffic to and from the rest of the world, while still allowing important services to run without disruptions.

That's the theory anyway. In practice, I assume Russian web services are just as dependant on third-party providers as the rest of us are.
