Ukrainian drones strike Yandex data center in Sasovo, causing fire and service outages
Ukrainian drones hit Yandex's Sasovo data center in Russia, igniting a large fire and forcing the facility to shut down. The site houses two Nvidia A100‑based supercomputers, Chervonenkis and Lyapunov, which power Yandex's AI models. Yandex says core consumer services stayed online, but users reported problems with Mail, Disk, Documents, Pay and Market, as well as many corporate customers. The company is urging customers to move workloads to alternative cloud zones while the fate of the supercomputers remains unclear.
Why it matters
The outage disrupts Yandex Cloud services for thousands of Russian businesses, potentially reducing revenue from cloud usage. If the supercomputers are damaged, Yandex may lose critical AI training capacity and could need to rely on foreign infrastructure, affecting its AI development roadmap.
