Third Yandex Data Center Shut Down After Consecutive Days of Ukrainian Drone Strikes

BLUFUkraine's sustained drone campaign against Yandex infrastructure is likely to hit at least one more data center by October 26, compounding outages across Russian state and commercial cloud services and stalling AI model development.

Yandex said on Sunday that a drone attack damaged its Vladimir data center and completely suspended operations, with no casualties, and described the remaining Yandex Cloud configuration as unstable and in emergency mode 12. Vladimir Governor Alexander Avdeev confirmed a drone attack on infrastructure near the city, a fire, and a power loss for about 5,000 residents, according to UA.News, which also reported more than 80 Yandex Cloud services down 3. This follows strikes on Sasovo in Ryazan Oblast on October 8, which Reuters and Meduza reported halted that facility and which houses two of the three supercomputers used to develop Yandex's AI model 456, and on Kaluga on October 9, where Yandex said several modules were completely disabled 56. Zelensky said on October 8 that Ukraine responds "in mirror-like fashion" to Russian strikes on Ukrainian data centers 26. Yandex has given no restoration timeline 35.

Analysis
Ukrainian drones will likely strike at least one more Yandex-operated data center, with Yandex or Russian officials confirming damage, by October 26. Confidence is high because three strikes in four days show a repeatable pattern, and Kyiv has publicly tied the campaign to Russian attacks on Ukrainian data centers. Surviving facilities now carry the displaced load, and Yandex calls its remaining Cloud configuration unstable. Sasovo matters most, since it hosts two of the three supercomputers used to train Yandex's AI model, so its restoration sets the pace for model development. Damage extent rests largely on company statements and unverified imagery. The three strikes may instead be an opportunistic burst against the most exposed sites, ended by air defense hardening and workload dispersal. If another strike is confirmed, Russian cloud-dependent operators and Western cyber and sanctions planners should treat Yandex infrastructure as a sustained target and shift to redundancy and impact assessment.
