Three drone attacks crippled Russian facilities, leaving users struggling with cloud files as businesses face uncertainty over recovery timelines and potential data loss.
Yandex has confirmed a major Yandex data center outage after drone attacks damaged three facilities in Russia, disrupting access to cloud files and business services. Two data centers stopped operating completely, while a third suffered partial infrastructure damage. The incidents affected Yandex Disk users and businesses relying on Yandex Cloud, raising concerns about service recovery and data availability, as reported by Yahoo Finance.
Three Russian Data Centers Hit by Drone Attacks
The disruptions began overnight on October 7 to 8, 2026, when an attack damaged Yandex’s Sasovo data center, forcing it to stop operating. Another incident struck the company’s Kaluga facility on October 9, disabling part of its infrastructure. A third attack hit the Vladimir facility overnight on October 11, halting its operations.
Yandex reported no injuries across the three incidents. Emergency responders and company specialists began working at the affected locations to assess the damage and support recovery efforts. In its official statement, the company said engineers were working around the clock to maintain services, although evaluating the damaged equipment remained difficult. Yandex did not provide a reliable timeline for restoring normal operations.
The company also warned that its cloud infrastructure remained unstable and that it was operating in emergency mode. Customers were advised to activate alternative disaster recovery plans while restoration work continued.
Yandex Disk Users Face File Access Problems
The Yandex Cloud disruption affected both individual users and enterprise customers. Reports described missing file thumbnails and failed downloads of previously uploaded content on Yandex Disk, with problems beginning on October 8. Some users also encountered HTTP 302 redirects, HTTP 504 Gateway Timeout errors and HTTP 500 errors when attempting to retrieve files.
However, failed downloads do not necessarily mean that files have been permanently deleted. The extent of any data loss remains unclear and the updates cited in BleepingComputer’s coverage did not establish whether customer files had been lost.
Business services also experienced interruptions. Yandex Cloud’s console, application programming interfaces (APIs), identity management, container registry, databases, S3 storage and Kubernetes reportedly faced performance or availability issues. Compute, AI Studio and security services were partly available, while Monium remained offline in the update cited on October 12.
These developments highlight the importance of cloud disaster recovery, infrastructure resilience and backup systems. Businesses that depend on a single cloud provider may face operational difficulties when physical facilities become unavailable. Yandex also cautioned that technical support channels could experience instability, making recovery coordination more challenging.
The available reports point to physical infrastructure damage and do not establish malware infections, stolen credentials, or unauthorized access to customer files. The situation remains dependent on repairs and service restoration, as reported by Yahoo Finance.
Thus, Business Fortune believes that the Yandex outage highlights the urgent need for resilient cloud infrastructure, reliable backups and effective disaster recovery plans.
