The Record reported on 12 October that Ukrainian drones hit a third Yandex data center in Russia overnight Sunday, this time in Vladimir. Yandex said the site shut down completely and its platform is running in emergency mode. Earlier strikes hit Sasovo, in the Ryazan region, on October 7-8, and Kaluga on October 9. The Record says the three sites hold about 115 megawatts of capacity combined. Russia's internet watchdog said users had trouble with email, taxi booking, food orders and Yandex Pay payments. The Record also reported problems at more than a dozen outside services, including TikTok's Russian segment.
The full scale is unclear. Yandex has not said how many customers were hit, though its cloud had about 64,000 in mid-2026. It also has not said whether its supercomputers were damaged. Yandex said a restore date is very hard to give. It told cloud customers to plan recovery beyond its own sites. Russian state media said it struck deals with Selectel, K2Cloud and VK Cloud. On Saturday, Yandex changed its terms to exclude liability for failures caused by drone strikes.
Yandex told customers not to rely only on switching between its own sites, and it limited its own liability. Teams that buy cloud services can check where their recovery copies live and what contracts say about attacks.
