Drone Strike Hits Third Yandex Data Center

Yandex's Vladimir facility - the third such site hit in a week - had its operations completely suspended after a single drone strike ^[1], underscoring how exposed data-center cooling and power systems are relative to hardened industrial sites. Digital rights lawyer Sarkis Darbinyan cautions against reading too much into the pattern nationally: because Russia's primary data infrastructure is concentrated and well protected around Moscow, a strike on a single regional facility "cannot take down a major service entirely" ^[2], meaning the damage is real but localized - hurting residents and B2B clients tied to that specific site more than the Russian internet as a whole.

The October 8 strike on Yandex's Sasovo facility reportedly knocked out two of the company's three AI supercomputers ^[3], and the Institute for the Study of War notes that Western sanctions and export controls could make it harder for Yandex to quickly replace the advanced semiconductors destroyed in these attacks ^[4], turning a one-time physical strike into a longer-term capacity problem for YandexGPT and the broader Yandex Cloud AI stack ^[5]. In the Vladimir strike alone, more than 80 cloud services - including databases, storage, and networking well beyond the AI API itself - went offline ^[1], underscoring how much of the country's AI infrastructure sits in a handful of exposed sites.

President Volodymyr Zelensky framed the strikes as a mirrored, proportional response to Russia's own attacks on Ukrainian data centers ^[6], and the timeline backs that framing: Sasovo on October 8, Kaluga on October 9 ^[7], and Vladimir on October 11 ^[1]- three hits on Yandex server hubs within roughly a week. Ukrainian arms maker Fire Point has said its FP-1 one-way attack drones were used in an earlier strike on what it called Yandex's biggest data center ^[8], though Ukraine's military has not officially confirmed responsibility, leaving attribution and the exact intended targets unverified in some coverage ^[9].

Despite no reported injuries ^[1], the Vladimir outage rippled straight into daily Russian life: the Yandex Go taxi app and Yandex Pro driver app went dark across Russia and neighboring countries ^[6], internet monitoring group NetBlocks measured national connectivity falling to roughly 70 percent of normal levels ^[9], and Yandex shares had already slid about 4 percent on the Moscow Exchange after the preceding Kaluga strike ^[10], with analysts warning that repeated attacks threaten revenue tied to the company's large B2B client base ^[11].
