## 🎯 Key Points

- A drone strike destroyed the Yandex data center in Sasovo, Ryazan Oblast.
- The outage paralyzed the websites of leading Russian media, banks, marketplaces, and state services.
- The Lyapunov and Chervonenkis supercomputers training Russian neural networks are at risk.
- Yandex shares on the Moscow Exchange plummeted by over 3%.

A large-scale outage has paralyzed the operations of leading Russian online platforms, corporate systems, and government resources following a drone strike on a strategic data center belonging to Yandex. The incident occurred on October 8, 2026, in the town of Sasovo, Ryazan Oblast, where a powerful fire broke out as a result of the UAV attack. The facility completely halted its operations, leaving millions of users without access to key digital services.

### Large-scale Runet Outages and Business Impact

The shutdown of the Sasovo data center triggered a chain reaction across Russia's digital space. Users are reporting widespread unavailability of the Yandex Cloud infrastructure, as well as email services, electronic storage, payment systems, and the marketplace. Furthermore, the technical collapse affected leading media outlets and propaganda resources, including Vedomosti, RIA Novosti, Kommersant, TASS, Interfax, and RBC, whose websites were completely blocked or experienced severe disruptions. Problems were also recorded in critical economic sectors: logistics giants Ozon and Wildberries, T-Bank banking systems, Russian Railways (RZD), Cian, and corporate software 1C and Astral all suffered disruptions.

### Threat to Supercomputers and Financial Blow to Yandex

Experts are particularly concerned that the affected facility in Sasovo housed two of Yandex's three supercomputers—Lyapunov and Chervonenkis—which are used in resource-intensive training for domestic neural networks. The Chervonenkis supercomputer, which once ranked in the prestigious Top-500 global list, is critical for the company's technological sovereignty. The company has not yet provided official data on the extent of the damage to the expensive server equipment. Amid the emergency, investors reacted instantly: Yandex shares on the Moscow Exchange plunged by more than 3%.

### Contradictory Data

While independent sources and Ukrainian media explicitly attribute the massive fire to a Ukrainian drone strike, Russian official structures and Yandex representatives in their public reports prefer to use vague formulations regarding an "incident at the data center" and "technical consequences of external impact," trying to minimize resonance surrounding the vulnerability of critical infrastructure. Nevertheless, eyewitness video footage confirms a powerful explosion and a plume of smoke visible for several kilometers from the restricted facility.

### Expert Assessments and Recovery Prospects

IT specialists note that restoring full operations of such infrastructure will take weeks, and in the event of damage to the supercomputers' processor modules, months of painstaking work. Sanctions pressure and a shortage of high-performance microchips significantly complicate repair logistics. The incident has demonstrated the high vulnerability of centralized digital systems belonging to big business and government agencies to physical attacks on data centers.
