Ukrainian Drones Knock Three Yandex Data Centers Offline in Russia, October 7-11, 2026
Between October 7 and 11, drone strikes hit three Yandex data centers. Yandex confirmed that the facilities in Sasovo and Vladimir shut down and that part of the infrastructure in Kaluga was knocked out. The Sasovo site in Ryazan region matters most for AI work, since it houses two of Yandex's three supercomputers used to train neural networks. Outages reached ordinary users: Downdetector logged more than 1,300 reports affecting Yandex Cloud, Yandex Documents and Yandex Tables, and Russians reported disruptions at banks, telecom providers, email services and food delivery payments. Yandex shares fell more than 3% on the Moscow Exchange. Ukraine has not claimed responsibility. President Zelensky called the strikes retaliation for Russian missile attacks on Ukrainian server facilities in Kyiv, saying, "We always respond symmetrically." Ryazan Governor Pavel Malkov said a roof caught fire at an unnamed company in the Sasovo district.
