Three Yandex data centers reportedly damaged or suspended after Ukrainian strikes

Damage or suspension at three sites within days

According to the article, a strike damaged a Yandex data center in the Sasovo region on October 8, another strike knocked out a Yandex facility in the Kaluga region on October 9, and a third strike reportedly forced Yandex to suspend operations at a Vladimir data center on October 11. The article says these sites housed Yandex supercomputers used for its YandexGPT AI model and that the incidents were followed by interruptions to a range of Russian digital services.

The article says Russia had launched drone attacks against Ukrainian data centers and telecommunications infrastructure in late September. It does not provide comparable measurements of service availability before and after the reported Yandex disruptions.

The report says three major Yandex data centers were damaged or had operations suspended over several days, with reported interruptions affecting Yandex-backed digital and cloud services.

The reported disruption concerns facilities supporting both AI computing and widely used online services. Russian commentators cited in the article characterize Yandex's concentration of infrastructure in a small number of large sites as a wartime vulnerability.
