Russian authorities held exercises to isolate the Russian internet segment (Runet) from the global internet, RBC news agency reports, citing sources and materials of the working group "Information Security" under Russia’s Digital Economy national program.
The exercises, which took place between June 15 and July 15, were attended by Russia’s "big four" internet providers (MTS, Beeline, Megafon and Tele2), as well as Rostelecom, Transtelecom and ER-Telecom Holding.
"The possibility of physical shutdown of the Russian segment of the Internet was tested," a source in the telecommunications market told RBC news agency .
According to another interlocutor of the news agency, "the exercises were successful." The official completion of the tests is scheduled for August 31.
In November 2017, Russian President Vladimir Putin demanded that an autonomous Internet governance system be developed that would remove the Russian internet segment out of the "dominance" of the United States.
