Yandex Data Center In Sasovo Halts After Drone Attack And Fire
The strike took out a facility that handles processing for Yandex's consumer services and holds the two machines used for its AI development, so the outage and the uncertainty around the hardware are the same story rather than two.

A Ukrainian drone attack before dawn on October 8, 2026 caused a fire at Yandex's data center in Sasovo, Ryazan Oblast, and Yandex halted operations at the facility. Yandex Cloud's ru-central-b zone lost power, with outages reported across email, online storage, document editing, Cian, Litmarket, the Russian Railways website, and Spartak Moscow's site. The site houses the Chervonenkis and Lyapunov supercomputers.
The outage reached past Yandex's own products. A bus operator in Moscow Oblast said it could not sell online tickets while the center was down, and the outage monitoring service Detector404 recorded 58,268 complaints over 24 hours, though not all of those are confirmed as caused by the attack. Yandex said search and ride-hailing kept running and advised cloud customers to move to a different operating zone. The company operates five large-scale data centers in Russia; Sasovo, southeast of Moscow, holds tens of thousands of servers. No casualties have been reported.
