Kremlin adds decentralized platform to its growing digital blacklist
In a move that further isolates its citizens from the global internet, Russia has officially blocked access to the decentralized social media platform Bluesky. The action was first reported on June 13, 2024, by Roskomsvoboda (RKS Global), a prominent Russian digital rights organization that monitors state censorship. The group confirmed that Bluesky’s domain had been added to the unified registry of banned websites maintained by Roskomnadzor, Russia’s federal communications watchdog.
This development is not an isolated incident but the latest step in a systematic and long-running campaign by the Kremlin to control the domestic information space. Since the full-scale invasion of Ukraine in February 2022, Russian authorities have aggressively moved to silence dissent and eliminate access to independent sources of news and information, blocking major platforms like Facebook, Instagram, and X (formerly Twitter), alongside hundreds of news outlets.
Technical mechanics of the block
The blocking of an online service in Russia is a state-mandated process that leverages the country's centralized control over its internet infrastructure. When Roskomnadzor adds a domain to its blacklist, it legally compels all Russian Internet Service Providers (ISPs) to prevent users from accessing it. This is typically achieved through several technical methods:
- DNS Filtering: The most basic method, where ISPs configure their Domain Name System (DNS) servers to refuse to resolve the blocked domain name (e.g., bsky.app) to its corresponding IP address.
- IP Address Blocking: A more direct approach where ISPs block all traffic to and from the known IP addresses associated with Bluesky's servers.
- Deep Packet Inspection (DPI): This is a more sophisticated and formidable censorship tool. Russian ISPs have been mandated to install DPI equipment as part of the country’s 2019 “sovereign internet” law. DPI allows authorities to inspect the content of data packets in real-time, identifying and blocking traffic destined for a specific service based on its unique signatures, even if users try to circumvent DNS or IP blocks.
Bluesky’s architecture, built on the decentralized AT Protocol, theoretically offers more resilience against censorship than traditional, centralized platforms. The protocol allows for a federated network of Personal Data Servers (PDS), meaning user data isn't held on a single central server. However, a determined state actor like Russia can still effectively neutralize access for the majority of users by blocking the main application domain, the primary PDS instances, and app store access. While technically advanced users might find ways to connect to smaller, unknown PDS instances, this is not a viable option for the general public.
Impact assessment: A shrinking space for free expression
The consequences of this block are significant and multi-faceted. The primary victims are Russian citizens, who now have one less avenue for accessing unfiltered information and engaging in free discourse outside the pervasive influence of state-controlled media. Platforms like Bluesky, while still nascent, were seen by some as potential havens for communities seeking to evade the stringent content moderation and surveillance present on other networks.
For Bluesky, the block curtails its growth in a major global market and presents a direct challenge to its mission of fostering open conversation. It also serves as a stark reminder that even platforms designed with decentralization in mind are not immune to the brute-force censorship capabilities of authoritarian states.
This action reinforces the Kremlin's overarching strategy of creating a “sovereign internet”—a digitally isolated ecosystem that can be meticulously controlled and, if necessary, disconnected from the global network. Each blocked service tightens the government’s grip, making it harder for independent journalists, activists, and ordinary citizens to organize, share information, and hold power to account.
How to protect yourself and maintain access
For individuals in regions with heavy internet censorship, regaining access to blocked services requires the use of circumvention tools. While no method is foolproof, especially against a state actively working to defeat them, several options remain viable.
- Virtual Private Networks (VPNs): A VPN encrypts your internet connection and routes it through a server in a different country. This masks your true IP address and makes your traffic appear as if it's originating from the VPN server's location, bypassing local ISP blocks. Using a reputable VPN service is a common first step for circumventing censorship. It is important to note, however, that Russian authorities are also actively working to identify and block VPN traffic, making this an ongoing cat-and-mouse game.
- The Tor Browser: Tor (The Onion Router) provides a higher level of anonymity by routing your connection through a volunteer-operated network of servers, wrapping it in multiple layers of encryption. This makes it extremely difficult for anyone to trace the traffic back to you. While often slower than a VPN, Tor is a powerful tool for accessing blocked content and protecting one's identity online.
- Alternative DNS Resolvers: Sometimes, simple DNS-based blocking can be bypassed by changing your device's DNS settings to a public resolver like Cloudflare (1.1.1.1) or Google (8.8.8.8). This method is ineffective against more advanced techniques like IP blocking or DPI but can be a quick first-line solution for simpler forms of censorship.
The decision to block Bluesky is a clear signal that the Russian government will not tolerate the existence of digital spaces it cannot control. As the Kremlin continues to build its digital walls, the struggle for a free and open internet within its borders becomes increasingly challenging.
