In early December, users in Russia began to have trouble accessing the Tor browser. After several days of technical difficulties, reports emerged that Russia's censorship agency (Roskomnadzor) had sent a notice to the Tor Project team, demanding that they remove unspecified "prohibited content." The project's landing website is currently blocked in Russia, while the Tor browser itself works intermittently. What does this mean for RuNet users? And is Roskomnadzor really capable of fully blocking the Tor browser? For answers to these and other questions, Meduza turned to Leonid Yevdokimov, a technical expert at the digital rights group Roskomsvoboda.
