Ukraine attack on Sber data centre hit Sberbank's data center and AI hub on Oct. 14 in Balakovo in the Saratov region, widening a wave of strikes on Russian digital infrastructure. People and businesses across Russia reported interruptions to cloud services, while banking, e-commerce, geolocation and ride-hailing systems also suffered lasting disruptions.
Mikhail Klimarev, head of the Internet Protection Society activist group, said, "This effectively sets Russia far behind in the AI race," after the attacks hit one Sberbank data center, three main data centers belonging to Yandex and one for VKontakte. He also pointed to damage that could take months, if not years, to repair.
Balakovo and the Sberbank hub
The strike in Balakovo landed on a facility that mattered for more than storage. Data centers are massive buildings packed with servers and the power and cooling systems that keep them running, so even a relatively light explosive load from a drone can produce lasting damage. That is why the Oct. 14 hit on Sberbank's site has been read as more than a one-off blast.
Ukraine struck the Sberbank site after a sequence that began on Oct. 8, when Ukrainian drones hit a Yandex data center in Sasovo in the Ryazan region that houses two of the company's three supercomputers. A data center in Kaluga was hit a day later, and the data center in Vladimir was struck on Oct. 11. Four days after the Balakovo strike, a data center in St. Petersburg serving VKontakte was also hit.
Russia's disrupted services
The reported fallout reached ordinary users and court systems at the same time. Cloud services were interrupted across Russia, and the disruptions stretched into banking, e-commerce, geolocation and ride-hailing. Alisa, Yandex's virtual assistant, and multimodal AI chatbots also suffered lasting interruptions, showing that the strikes reached services built on the same backbone as consumer apps and corporate tools.
Arbitration courts were forced to cancel or postpone sessions and cut database access, adding a practical layer to the technical damage. That is the part customers and businesses now have to work around: transactions, lookups and automated tools may keep failing until damaged infrastructure is repaired or moved onto other systems.
Yandex, Sberbank and VKontakte
Yandex, Sberbank and VKontakte have been described as coy about the damage even as users and businesses reported widespread service interruptions. Kyiv's attacks on Russian data centers closely followed Moscow's recent strikes on data centers in Ukraine, after Russian missiles and drones pummeled Ukraine's power grid and other key sites.
Ukraine also hit huge warehouses for Russia's top online retailers, Wildberries and Ozon, expanding the campaign beyond data centers and into other digital and logistics infrastructure. The pattern suggests a wider attempt to pressure Russia's online economy by targeting the buildings that hold the servers, backups and cooling systems behind everyday services.
For users and businesses, the immediate issue is not the headline strike itself but whether Sberbank's AI and cloud operations can stay online as repairs drag on. Most experts predicted the damage could take months, if not years to fix, and the Balakovo strike left that repair clock running against Russia's most sensitive digital systems.
