Overview
- Yandex said the Sasovo facility in Ryazan Oblast was hit by a drone on Thursday and that the data centre has stopped operating while emergency teams work on-site and no casualties were reported.
- The company reported power-supply problems in its ru-central1-b availability zone that produced disruptions for cloud services and prompted customers to move workloads to other zones.
- OSINT groups and regional officials identified the site as colocated with the Sasta machine-tool plant, a sanctioned maker of high-precision CNC machinery used by Russia’s defence industry.
- Attribution remains contested because Yandex did not confirm the strike’s origin while Ukraine’s Center for Countering Disinformation publicly signaled Kyiv responsibility and Russia’s Defence Ministry said its forces intercepted hundreds of drones overnight.
- The incident sharpens technical and strategic risks for users of Russian cloud and AI infrastructure and raises second-order concerns about communications resilience, service continuity for enterprises and reliance on OSINT and official claims for attribution.
