What happened
Ukrainian drone strikes hit Yandex data centers in Sasovo, Kaluga, and Vladimir between October 8 and 11, 2026. The attacks caused fires and led to the suspension of operations at the Sasovo facility. Yandex confirmed that over 80 cloud services went offline, and automated traffic from the company's network declined.
Why it matters
The physical damage to Yandex's infrastructure caused service disruptions for users of Yandex Cloud and other services. Following the incident, Yandex shares dropped more than 3.4% during morning trading on the Moscow Exchange.
Commercial warnings were issued after drone operations impacted Russian airspace, which has led to stock market falls and airline warnings.
