## AI overview

Yandex says 2.84% of customer data was permanently lost after strikes damaged data center equipment, with recovery impossible because affected data lacked platform backups. Customers who had enabled backups retained their data. In response, Yandex Cloud will enable automatic backups by default for new virtual machines, while allowing customers to disable them in the management console. It also announced a separate-location availability zone, ru-central1-f. These changes address backup defaults and service resilience; the excerpt does not establish their effectiveness.

## Source excerpt

Russia's Yandex says 2.84% of customer data has been permanently lost following Ukrainian strikes on data centers in the country. "According to the company, recovery is impossible because of critical damage to equipment and the lack of backup copies on the platform," reports UNITED24 Media. From the report: Yandex clarified that customers who had previously enabled the platform's backup tools did not experience any data loss, as their information remained fully preserved. The incident has prompted the company to revise its approach to data protection and disaster recovery, particularly the default settings for cloud infrastructure. Under the updated policy, automatic backups will be enabled by default whenever customers create new virtual machines on Yandex Cloud. Users will retain the option to disable the feature manually through the management console. In addition to changing its backup policy, Yandex Cloud announced the launch of a new availability zone, designated ru-central1-f. The new availability zone operates from a separate location, improving the resilience and reliability of the services. The report says Ukrainian drones targeted three Yandex data centers in Russia over four days, beginning October 8 with a strike on a facility in the Ryazan region that houses two of the company's three supercomputers. A second attack hit Yandex's largest data center in the Kaluga region on October 9, followed by a third strike on October 11 targeting a facility in the Vladimir region that houses the company's remaining supercomputer.
