Overview
- Early on Thursday, October 8, open-source analysts and local footage showed a large fire at the Sasta complex in Sasovo, Ryazan Oblast, and Yandex confirmed a drone caused the blaze and that the data centre’s operations were fully suspended with no casualties.
- Yandex Cloud logged an ‘incident’ and power-supply problems in its ru-central1-b availability zone beginning at about 1:31 a.m., and outage monitors recorded spikes in reports for cloud products even though core consumer services remained largely online.
- OSINT groups Exilenova+ and ASTRA geolocated the strike to the Yandex site, a Ukrainian disinformation official posted that Kyiv forces struck the facility, and Russian regional authorities said they shot down drones over Ryazan, leaving public attribution contested.
- The data centre sits on the grounds of the Sasta machine-tool plant, a sanctioned supplier of high-precision CNC machines to Russia’s defence and aerospace sectors, which blurs the line between civilian tech infrastructure and military-linked industry.
- The attack heightens the risk of further disruptions to cloud-hosted services and AI workloads, so users and businesses should monitor Yandex restoration updates and be prepared for possible reciprocal strikes and wider outages this winter.
