Summary

A fire broke out at a Yandex data centre in Sasovo, Ryazan region, on October 8, 2026, following what multiple reports describe as a Ukrainian drone attack. Ukrainian President Volodymyr Zelensky stated that Ukraine carried out the strike in response to Russian attacks on Ukrainian data centres. The fire forced Yandex to suspend operations at the facility, though the company stated its core consumer services were not affected. The attack caused widespread internet disruptions across Russia, affecting banking, online platforms, mobile operators, retail websites, and Russian Railways, with complaints concentrated in St. Petersburg and Moscow. Yandex warned that full service restoration could take up to 24 hours. The data centre is located on the grounds of the Sasta machine-tool plant. Some reports indicate uncertainty about whether the Yandex facility, the Sasta plant, or both were the intended targets.
