Overview
- A drone attack hit a Yandex data center in Sasowo in the Ryazan region, causing a roof fire and forcing the facility to suspend operations, the company said.
- Yandex Cloud reported power failures in part of the site and asked customers to move critical applications to other locations where possible.
- The data center sits on the grounds of the Sasta machine-building plant, which makes precision tools used by Russia's defense and aviation sectors, creating uncertainty over whether the strike targeted industry, commercial cloud infrastructure, or both.
- There were no reported injuries, and a former Ukrainian disinformation official publicly claimed responsibility, but formal attribution remains unconfirmed and politically sensitive.
- The outage could disrupt services that rely on Yandex Cloud and has been framed by reporters as the latest example of intensified long-range strikes on rear-area infrastructure, which may prompt further service migrations and security reviews.
