On March 10, 2026, mobile internet connectivity across the Russian Federation experienced significant disruptions. The outages primarily affected major urban centers including Moscow and Saint Petersburg, as well as several southern regions bordering Ukraine, including Belgorod and Rostov. According to data from network monitoring services, mobile data traffic began dropping sharply at approximately 04:00 local time. The disruption impacted the country’s four major telecommunications providers: MTS, Megafon, Beeline, and Tele2. Reports indicate that while voice calls and SMS remained functional, 4G and 5G data services were either completely severed or severely throttled.
Technical analysis suggests the use of Technical Means of Countering Threats (TSPU) hardware, which allows the state regulator Roskomnadzor to filter and block internet traffic at the packet level. Users reported total loss of access to encrypted messaging platforms, including Telegram and WhatsApp. Furthermore, several Virtual Private Network (VPN) protocols, specifically OpenVPN and WireGuard, were reportedly blocked via Deep Packet Inspection (DPI). The outage has affected digital payment systems, ride-hailing applications, and logistics coordination platforms. Estimates from digital rights groups suggest that over 60 million mobile subscribers have been affected by the regional blackouts.
Kremlin spokesperson Dmitry Peskov confirmed the restrictions during a press briefing on March 10, stating that the measures were necessary for ensuring national security amid unspecified threats. He did not provide a timeline for the restoration of full services. Roskomnadzor issued a brief statement noting that preventative security measures were being implemented in coordination with law enforcement agencies. These measures follow a series of localized shutdowns in late 2025, but the scale of the March 10 event represents the most significant disruption to the Russian domestic internet infrastructure in recent years.
The outage has reportedly impacted civilian-grade communication tools often utilized for logistical support in the ongoing conflict. At the market open on March 10, the VIX volatility index rose 35.5 percent to 29.5, reflecting elevated global uncertainty.
