Yandex users may have lost their data for good following Ukraine strikes — Russian tech giant confirms 2.84% of customer data is gone forever
Yandex recovers 97.16% of customer data after Ukrainian drone strikes, but equipment damage and missing backups left remaining information permanently inaccessible.
Yandex, a Russian tech giant, has confirmed that 2.84% of customer data was permanently lost following Ukrainian drone strikes on its data centers. The company recovered 97.16% of the affected data. Ukrainian drones targeted three of Yandex's supercomputers - Chervonenkis, Lyapunov, and Galushkin - located in three different facilities.
The attacks began on October 8, 2026, with strikes on a facility in Sasovo, followed by attacks on October 9 and 11 at facilities in Grabtsevo and Vladimir, respectively. Yandex has introduced automatic backup protection for new virtual machines and added another availability zone to enhance service continuity. Some Russian businesses are considering hosting their operations outside Russia, citing concerns about further damage to their domestic computing infrastructure.
