Summary

A drone attack disabled several modules at a Yandex data center in Russia's Kaluga region on October 9, marking the second such incident at a Yandex facility in two days following a strike on a center in Ryazan region on October 8. Yandex reported service disruptions and damage to infrastructure. Casualty reports differ: most sources report no injuries, while one report cites nine people injured and another mentions injuries in Kaluga without specifying the facility. Ukraine has not confirmed responsibility for the attacks. Russian users reported temporary disruptions to internet services, banking platforms and telecommunications networks. Both Russia and Ukraine have expanded drone attacks on economic targets, including data centers, in 2026.
