Yandex runs Russia's main search engine, the Alice AI assistant, advertising and more than 100 other services, from grocery delivery to cloud computing. In October 2026 Ukrainian drones struck two of its data centres, at Sasovo and Kaluga.
Its Russian parent, IPJSC Yandex, has traded on the Moscow Exchange as YDEX since July 2024. That month the Dutch holding company Yandex N.V., now Nebius Group, sold the Russian businesses to a consortium of Russian investors for about $5.4bn, and the two are now separate companies. Revenue in the second quarter of 2026 was 386bn roubles, up 16% on a year earlier.
The data centre strikes made Yandex a direct target of Ukraine's long-range campaign, which Kyiv had already widened beyond oil in July with strikes on Wildberries logistics hubs.
Drones hit Yandex's AI computing base
Yandex lost capacity at two sites in two days. On 8 October 2026 drones knocked out its Sasovo data centre in Ryazan region, which houses two of the three supercomputers it uses to train its artificial intelligence models. On 9 October it reported that modules at Kaluga, its largest data centre, had been knocked out completely, with no injuries and no timeline for repairs.
Zelenskyy called the strikes "our symmetrical response" to Russian attacks on Ukrainian data centres. For Yandex the damage reaches the AI work behind products such as the Alice assistant, as well as the search, maps and cloud services that millions of Russians use daily.
