Ukrainian Drones Strike Yandex AI Data Centers

Ukrainian drone strikes damaged two of five Russian data centers owned by tech giant Yandex on October 8 and October 9, directly impairing the infrastructure used to train its YandexGPT artificial intelligence model. The attacks targeted facilities in the Sasovo and Kaluga regions, leaving the company struggling to maintain its online services alongside its primary AI chatbot.

According to reports, the strikes utilized FP-1 one-way attack drones manufactured by the Ukrainian enterprise Firepoint. The attack on the Kaluga site targeted Yandex's largest data center facility. Meanwhile, the earlier strike against the Sasovo location damaged a building housing two of the company's three supercomputers dedicated specifically to training YandexGPT. Although Yandex acknowledged service disruptions, the firm reported that no employees were injured in the strikes.

The physical damage to the data centers caused immediate operational fallout throughout Russia. In addition to affecting YandexGPT, the disruption compromised access to popular media websites, the Ivi video streaming platform, digital banking through T-Bank, and the state-owned Russian Railways network. Affected platforms also included a dating app, a real estate aggregator, a self-publishing book service, and the official website of the most successful soccer club in the Russian Premier League.

Ukrainian President Volodymyr Zelenskyy referred to the action on X as a "symmetrical response" to Russian strikes targeting Ukrainian data infrastructure, which have degraded mobile phone and internet connections for thousands of citizens since late September. For machine learning practitioners and cloud operators, the event highlights how critical compute nodes, supercomputers, and training pipelines are becoming frontline targets in contemporary military conflicts.
