Ukrainian drones hit Yandex data centre and Omsk refinery

The drone attack on Yandex's Sasovo hub in Ryazan region, overnight into Thursday, 8 October, started a fire and fully halted a site that hosts tens of thousands of servers; no one was hurt. Reuters calls it the first major attack on a Russian data hub since the war began. Yandex Cloud customers such as Cian, Russian Railways and T-Bank were disrupted, and RBC reported that sites including Kommersant and Vedomosti briefly stopped loading. Yandex says its core consumer services were unaffected but cannot yet say whether the equipment can be restored. It declined to say whether two of its three supercomputers, which train AI models and are housed there, were damaged. Its shares fell more than 3%.
