GoKawiilYandex Cloud loses 2.84% of customer data after Ukrainian drone strikes
Yandex confirmed that Ukrainian drone strikes on three of its Russian data centers in October caused permanent loss of 2.84% of customer data, since the affected systems lacked backup copies. Customers who had enabled Yandex Cloud's backup tools retained their data fully. In response, Yandex will make automatic backups the default setting for new virtual machines and is launching a new availability zone, ru-central1-f, at a separate location.
GoKawiil's interpretation of the reporting above, not reported fact.
The strikes highlight how Ukraine's drone campaign is reaching beyond military and energy targets into Russian digital infrastructure, including facilities reportedly housing supercomputers. Yandex's policy shift toward default backups suggests the company is treating the risk of further physical attacks on its infrastructure as an ongoing operational concern rather than a one-off event.
- Yandex lost 2.84% of customer data permanently due to strikes on three Russian data centers.
- Customers using existing backup tools suffered no data loss, prompting Yandex to make backups default going forward.
- A new availability zone, ru-central1-f, is being added to improve resilience against future disruptions.
