Overview
- Yandex said a drone caused a fire at its Sasovo data centre in Ryazan Oblast and that the facility has been fully suspended with emergency crews on site.
- Regional governor Pavel Malkov reported Ukrainian drones were shot down over Ryazan and that a roof fire occurred in Sasovo, while OSINT groups Exilenova+ and ASTRA identified the site as the Yandex DC on Sasta plant grounds.
- Ukraine's Center for Countering Disinformation published a Telegram post claiming responsibility and saying 'two can play at this game', though Yandex did not specify who launched the drone.
- Outage monitors logged spikes in user complaints and Yandex reported power and cloud-service disruptions that affected Yandex Cloud, Documents and Tables while core consumer services largely stayed online.
- The Sasovo complex houses Sasta, a sanctioned maker of high-precision CNC machines used by Russia's defence and aerospace sectors, and the strike raises the risk of further targeting of cloud infrastructure and broader service impacts.
