俄羅斯's 網際網路審查 is administered by Roskomnadzor (the 通訊監督聯邦服務). Since the invasion of Ukraine in 2022, censorship has escalated dramatically. The government has blocked Facebook, Instagram, Twitter, and dozens of independent news outlets. VPN services are targeted, with Roskomnadzor requiring VPN providers to connect to the government's censorship infrastructure or face blocking.
The blocking of 中的 Tor December 2021 was a significant escalation. Roskomnadzor added torproject.org to its registry of banned websites and began blocking known Tor 中繼 IP 位址 using the TSPU (Technical Means of Countering Threats) - DPI equipment installed at major internet exchange points. By 2023, 俄羅斯 had also begun deploying more sophisticated traffic analysis to detect Tor 橋接 connections.
Despite this, 俄羅斯's Tor blocking is less comprehensive than 中國's 防火牆. The DPI infrastructure is unevenly deployed, and many ISPs have incomplete implementations. This means that pluggable transports that fail in 中國 may still work reliably in 俄羅斯, giving users more options for circumvention.
