Summary

A drone attack on a Yandex data center in Kaluga, southwest of Moscow, on October 9 disabled several modules at the facility, the second such incident at a Yandex data center in two days. Yandex reported that some services may experience disruptions. Reports differ on casualties: most sources report no injuries, while one account mentions nine people injured in Kaluga. Ukraine has not confirmed responsibility for the attacks, though Russian authorities attributed the earlier attack on a Yandex facility in Ryazan to Ukraine. Russian users reported temporary disruptions to other Internet services, banking platforms, and telecommunications networks following the incidents. Both Russia and Ukraine have expanded drone attacks on economic targets, including data centers, in 2026.
