According to BBC, this massive exercise is slated to take place before 1st April 2019; however, no exact date has been announced. As per this internet traffic routing, only Russian websites will be able to work.
The draft legislation would allow Moscow effectively to turn off the external internet - sites and services based on servers overseas - and filter traffic, while the Russian internet functioned autonomously. ZDNet also highlights that under the law, telecom groups would have to install a means to counter a cyber attack threat, largely by rerouting all Russian traffic to exchange points overseen by Russia's federal communications regulator (and censorship mechanism) Roskomnadzor.
North Atlantic Treaty Organisation and Western allies have warned Russian Federation they would impose sanctions over cyber attacks and online interference.
The Russian government will compensate ISP to modify their infrastructure so that the redirection effort can be properly tested. Russian Federation has been building its own localized Domain Name System (DNS) for a few years now.
Russian authorities and internet providers are going to shut down Russia from the rest of the internet. They fear major disruptions and therefore inconvenience to Russian internet traffic during the trial run. The legislation is supported by Russian President Vladimir Putin and is expected to pass through parliament.
It would gather data as politicians assess the Digital Economy National Program, a draft law that would require the country's internet providers to ensure that Russia's internet can operate in isolation if a foreign power cuts it off.
The goal of the test is to make sure that traffic doesn't leave Runet, and can't be re-routed via servers in other countries, where it could then be intercepted.
Supporters say the proposal is necessary in case Russian Federation was to be cut off from the global internet, but opponents fear the measure would lead to widespread censorship.
As a result, the Russian government began working on defence tactics years ago.
While proponents of the Russian internet project say it would protect the country from losing access to the web amid a US blackout, the plan would also block Russian internet users from anonymizing their identity and location using virtual private networks - a key tool used to access uncensored content and enable private communication.
