Following the refusal by Telegram to provide the keys to its encrypted message services, the Tangansky court in Moscow on Friday 13 of April moved to ban the messenger app from operating in Russian Federation.
Durov, however, warns that banning Telegram could actually compromise Russian state security and the security of 15 million Russian Telegram users.
A spokeswoman told Reuters that France wanted an app whose encryption isn't controlled by the U.S. or Russian Federation.
Amid the dragnet blocking by RKN, some people and companies, including Telegram competitor Viber, complained online that the measures affected other services which used Amazon and Google infrastructure.
Also, Telegram has the capabilities for users to encrypt their personal and business information and enables the users to destroy their messages with a timer.
It was expected to take several hours for the process to be completed.
Over 1.8 million Amazon and Google-owned IPs have been blocked so far.

The third point of the court decision requires Roskomnadzor to not create the conditions for the technical access to the blocked messenger.
Durov, a pioneer of social media in Russian Federation, left the country in 2014 and has become a vocal critic of the Kremlin's policies on internet freedom.
For example, it has been used in the past to set up conference calls between officials and reporters. Russia's main security agency, the FSB, has said Telegram is the messenger of choice for "international terrorist organisations in Russia". Removing an app as the result of a country's request would not be unprecedented, though.
The move to ban IP blocks is a response to Telegram moving some of its infrastructure to Amazon Web Services and Google Cloud servers over the weekend. However, many other Russian businesses use them too, and they suffered as millions of IP addresses became blocked.
