Overview
- A drone strike on Oct. 8 ignited a fire at Yandex’s Sasovo data centre in Ryazan Oblast, forcing the facility to stop operating while emergency teams worked on site and no casualties were reported.
- Yandex reported power‑supply problems in its ru-central1-b cloud zone, warned customers that some services may be unavailable, and advised moving workloads to other zones as engineers assess damage.
- Reuters and Yandex said a separate drone attack on Oct. 9 disabled several modules at a Kaluga‑region data centre, marking two hits in two days and signalling a rapid escalation.
- OSINT groups and regional officials identified the Sasovo site as being on the grounds of the Sasta machine‑tool plant, a sanctioned maker of high‑precision CNC equipment that gives the complex a dual‑use military and commercial profile.
- The strikes form part of a wider tit‑for‑tat campaign of long‑range attacks on data and telecom infrastructure that could further disrupt civilian connectivity and industry services ahead of winter.
