Summary

Ukrainian forces conducted drone strikes against Yandex data centers located in Sasovo, Kaluga, and Vladimir, resulting in significant operational disruptions and damage to the company's infrastructure. The attacks caused outages for various Yandex services, including search indexing and the Yandex Go superapp, affecting users in Russia and Central Asia. While the strikes led to a notable drop in traffic for Yandex Search (AS13238), researchers noted that malicious bot activity migrated to other providers rather than ceasing. Yandex is currently working to address the consequences of the strikes, though recovery efforts may be prolonged by Western sanctions impacting the availability of necessary equipment.
