Yandex said it had restored 97.16% of Yandex Cloud customer data and could not recover the remaining 2.84%, Reuters reported on November 10, 2026. The company attributed the unrecoverable data to critical equipment damage and customers lacking backups on the platform.
Data recovery and infrastructure resilience are different jobs: Yandex described changes to both backups and resource locations.
What the percentages measure
Yandex described both figures as shares of customer data: 97.16% restored and 2.84% unrecoverable. The figures concern data, not a percentage of customers.
The losses followed damage to three Yandex data centers in Ukrainian drone strikes in early October 2026, Reuters reported. NeoTeo previously covered Yandex Cloud’s emergency status on October 12; this follow-up concerns the later recovery figures.
Yandex’s reported backup and infrastructure response
Yandex said it planned to enable backups by default. In its November 10 account, the company also said engineers were distributing Yandex Cloud computing resources across additional independent locations in different regions of Russia.
