Russia on Wednesday started blocking the Tor network, which allows users to browse the internet anonymously.

The website of The Tor Project, the organization behind the browser, is also no longer available in the country.

With the Tor network, internet traffic is sent over several encrypted 'shells' to ensure user anonymity.

The browser ensures, among other things, that placed cookies can be linked to each other less easily.

Also, browsing history is cleared after each use.

Russian regulator Roskomnadzor says the Tor network "provides access to illegal content".

Earlier this month, the watchdog decided that all providers had to block access to the network.

Russia has the second largest number of daily users of the Tor network, at around 300,000.

That's about 14 percent of the total number of Tor users.

Since this year, Russia has been trying to get a better grip on large tech companies.

Earlier this year, Twitter was intentionally slowed down because the service did not comply with Russian rules.

The company initially did not remove illegal content, after which the loading times of the social medium increased significantly.
