Shustree Works in Mobile Networks Independent of TSPU / DPI

The Shustree team has completed a full transition to an updated mobile traffic routing architecture. The implemented framework provides stable, high-speed, and uninterrupted access to international information resources across mobile telecom networks in Russia, Kazakhstan, the Republic of Belarus, Uzbekistan, Kyrgyzstan, Turkmenistan, and Tajikistan.

Network Routing Architecture and Fault Tolerance

The new network traffic processing model was engineered considering the specifics of Deep Packet Inspection (DPI) systems and TSPU (Technical Means of Countering Threats):

• Primary Traffic Aggregation: All incoming user flow is routed through high-performance Shustree nodes in Saint Petersburg, hosted within the fault-tolerant infrastructure of Selectel data centers.
• Selective International Routing: Network traffic directed to resources and services that are not legally restricted within the Russian Federation (including Gemini, ChatGPT, Google Flow, Claude, WhatsApp, YouTube, and other essential productivity tools) is redirected to targeted Shustree servers deployed in specialized Tier III Google Cloud data centers in Europe, as well as core Selectel data centers in Uzbekistan.

Thanks to direct L4/L7 route management and the complete abandonment of BGP Anycast technology (an analysis of Anycast architecture vulnerabilities is detailed in our article), the Shustree infrastructure demonstrates high resilience against network degradation and DPI blocking at the mobile carrier level.

Legal Compliance and Regulatory Status

Shustree strictly complies with the legislation of its operating jurisdictions and functions exclusively within the legal framework:

• Content Legitimacy: The service exclusively routes legitimate traffic to information resources that are not restricted by court orders or regulatory acts of the Russian Federation.
• Legal Guarantees: Restricting access to blocked resources eliminates legal grounds for imposing restrictions on Shustree's infrastructure by the FSB, MIA, or other federal executive bodies, including Roskomnadzor.
• Privacy & Confidentiality: Granting access to server infrastructure or user data without statutory court orders is strictly prohibited by service architecture and terms of service.
