On 10 March 2021, Roskomnadzor started to “slow down” Twitter for users in Russia, attributing the decision to the platform's failure to remove illegal content. This action occasionally caused Russia's key websites, including Roskomnadzor itself, to stop working. It also led to malfunctions of major commercial services, such as Qiwi payment system, and blocked some users from accessing Yandex, Google, and YouTube.
