Drone attack disabled modules at Yandex data centre in Kaluga, Russia

Situation Overview

On 9 October 2026, a drone attack disabled modules at the largest Yandex data centre in Kaluga, Russia, according to a Telegram post. The Kaluga site is described as nearly 5.2 times more powerful than Yandex’s data centre in Sasovo. The post says the Kaluga facility provided the bulk of Yandex’s cloud computing and services and that its total designed power is 63 MW. It characterises the site as the largest data centre for Yandex and for Russia, and equates 63 MW to power for roughly 150–250 large apartment buildings. No further confirmed details on repair timelines, service restoration, or casualties were provided in the cluster.
