Ukraine has struck three major data centers owned by Russian tech company Yandex in recent days, including a facility in Sasovo that houses supercomputers used to train Yandex's AI model. President Volodymyr Zelenskyy described the strikes as a 'symmetrical response' to Russia's own drone campaign against Ukrainian data centers and telecom networks that began in late September and disrupted service for up to 100,000 households in Kyiv.

Yandex confirmed that drone attacks damaged three of its data centers in Sasovo, Kaluga, and Vladimir between October 8-11, knocking two facilities offline entirely and degrading the third. Customers have reported being unable to access files stored on Yandex's cloud infrastructure, and the company says it cannot give a reliable timeline for restoring service. Yandex has urged customers to switch to alternative disaster-recovery infrastructure while its teams work to stabilize the remaining systems.

Following Ukrainian drone strikes on Russian data centers, a Cloudflare chart showing a drop in Yandex-related bot traffic spread widely on social media, with many assuming it showed Russian disinformation bots going offline. Researcher antibot4navalny says the data actually reflects a decline in Yandex's own web crawler activity, not social media bot farms, and that broader Russian bot traffic was largely unaffected. A separate chart claiming to show a drop in pro-AfD online activity, shared by EU lawmaker Tomáš Zdechovský, has been flagged by computer scientist Raphael Wimmer as possibly AI-generated.
