Ukrainian Drone Strikes Cripple Russian Data Centers, Disrupt Everyday Services
By Drooid · · How we work
The Strikes and Immediate Fallout
In early October 2026 Ukrainian drones targeted three Yandex data centers—Sasovo in the Ryazan region (Oct 8), Kaluga (Oct 9) and Vladimir (Oct 11)—as well as a Sberbank AI hub in Balakovo and a VKontakte facility in St. Petersburg. The attacks knocked offline the facilities that host two of Yandex’s three supercomputers and a major banking cloud platform. Across Russia, cloud-based services for banking, e-commerce, ride-hailing, geolocation and Yandex’s virtual assistant Alisa experienced prolonged outages. Arbitration courts were forced to cancel or postpone sessions, and many users lost access to digital wallets, taxi apps and personal data.
Background & Context
Data centers have become a focal point of the aerial war between Kyiv and Moscow. Russia’s earlier strikes on Ukrainian data sites disrupted internet and TV broadcasts, prompting Kyiv to retaliate with drones aimed at Russia’s digital backbone. The Russian government’s “digital sovereignty” policy mandates that all data be stored domestically, concentrating critical infrastructure in a few large facilities and making them vulnerable to aerial attacks.
Timeline of Key Events
- Oct 8 – Drone strike shuts down Yandex’s Sasovo center, home to two supercomputers.
- Oct 9 – Partial damage to Yandex’s Kaluga campus; no immediate drop in online activity recorded.
- Oct 11 – Complete halt of Yandex’s Vladimir site after a second drone strike.
- Later in October – Sberbank AI hub in Balakovo hit.
- Mid-October – Kyiv strikes a VKontakte data center in St. Petersburg.
Official Statements & Responses
The company reported no injuries and said it was working to restore service.
On-the-Ground Reports
Moscow resident Igor Mann could not collect an order from Yandex Market, and taxi driver Pavel Belyavskiy was unable to connect with passengers for hours. Another user, Irina, reported being locked out of her Yandex Pay account for several days, prompting her to diversify her deposits.
Conflicting Reports & Gaps
Yandex has not disclosed the full extent of damage, yet satellite imagery shows serious fires and structural harm at the Sasovo and Vladimir sites. The CCD’s claim of an 84 % bot-activity collapse is contested by independent analyses that attribute most of the traffic drop to automated search crawlers rather than coordinated disinformation accounts. No definitive public data confirm how much of Yandex’s AI hardware was destroyed versus merely disabled.
What’s Next
Klimarev predicts the strikes could push many Russian companies to move data storage to Europe and may lead authorities to relax internet-control measures to mitigate future disruptions. No concrete timeline for full restoration has been provided.
