To block websites, OONI data shows that Russian ISPs adopt the following censorship techniques (beyond throttling):.Some ISPs implement blocks through the use of multiple techniques at the same time, making circumvention harder. As a result, we observe variance in how internet censorship is implemented across Russia, as blocks are not implemented on all networks in the country, and different ISPs adopt different censorship techniques. Decentralized censorship. Every Internet Service Provider (ISP) in Russia is responsible for implementing government-mandated blocks independently.Blocking of Facebook and Twitter. OONI data shows that access to and was blocked in Russia by 4th March 2022 (primarily through the injection of RST packets).Moreover, interference to appears to have changed from throttling to blocking (through the injection of a RST packet) on 4th March 2022. As the throttling of seems to have stopped across all ISPs in Russia at the same time (~08:00 on 4th March 2022 UTC), it appears to have been centralized. Centralized throttling of Twitter. OONI data suggests that access to was throttled in Russia between 26th February 2022 to 4th March 2022.Blocking of a website about captured and killed Russian soldiers. Russia blocked access to, which was created by representatives of the Ministry of Internal Affairs of Ukraine to share information about captured and killed Russian soldiers in Ukraine.Media censorship. Russia recently started blocking access to independent Russian news media websites (such as Dozhd and New Times) and foreign news media websites (such as BBC, Deutsche Welle, Russian version of Voice of America, and Russian service of Radio Liberty).Blocked website about captured and killed Russian soldiers.Radio Free Europe/Radio Liberty (RFE/RL) service websites. ![]() In this report, we share an in-depth analysis of new censorship events that have recently emerged in Russia based on OONI network measurement data. Censorship in Russia is generally implemented in a decentralized way, as blocks are not observed on all networks, while ISPs adopt a variety of different censorship techniques. OONI data also shows that Russian ISPs started throttling access to Twitter on 26th February 2022, and switched to blocking it by 4th March 2022 – at which point, they also started blocking access to Facebook. In recent days, OONI network measurement data collected from Russia shows that many Internet Service Providers (ISPs) have started blocking access to several news media websites, as well as to a website () that shares information about captured and killed Russian soldiers in Ukraine. Information controls are known to occur during conflicts, and that’s exactly what we’re seeing in Russia following the recent invasion of Ukraine on 24th February 2022. ![]()
