Ukraine Strikes Russian Data Centers, Disrupting Online Services
What Happened
Between October 8–12, 2026, Ukrainian drones struck at least three Yandex data centers in Sasovo (Ryazan region), Kaluga, and Vladimir, disabling servers and sparking fires. Yandex confirmed that its Sasovo hub housing AI supercomputers was shut down, while the Kaluga site was partly disabled. The attacks disrupted services including Yandex Pay, Yandex Go taxis, food delivery apps, and cloud computing used by thousands of businesses. Reuters reported that startups lost access to backup databases, while Le Monde noted that replacing damaged equipment could take up to six months. Ukrainian officials framed the strikes as retaliation for Russian attacks on Ukrainian digital infrastructure.
Key Takeaways
The strikes highlight the digital dimension of the war, with Ukraine targeting Russia’s tech backbone. Disruptions to Yandex’s cloud and payment systems show how attacks on data centers can impact daily life and business operations, extending the battlefield into cyberspace.
