Summary

Ukrainian forces conducted drone strikes against Yandex data centers in Sasovo, Kaluga, and Vladimir, causing significant operational disruptions and infrastructure damage. The attacks affected Yandex Search (AS13238) and various services, including ride-sharing and food delivery apps, leading to outages in Russia and Central Asia. While Ukrainian President Volodymyr Zelenskyy claimed the strikes reduced pro-Russia bot activity, researchers found that the impact was limited to the disruption of Yandex's search indexing software rather than a decrease in social media disinformation campaigns. Yandex is working to restore services, though recovery efforts face potential delays due to sanctions.
