Yandex Data Center Attacks Trigger Outages, Cloud Disruptions and Stock Decline
A series of physical attacks has disabled or partially damaged multiple Yandex data centers in Russia, leading to prolonged service outages across cloud and consumer platforms. Fires and power failures struck facilities in Sasovo, Kaluga and Vladimir between 8 and 11 October, forcing the company to shift workloads to the remaining Mytishchi site. Analysts from Finam, Rikom-Trust and Freedom Global note that recovery timelines now stretch from several months to two years for specialized hardware such as supercomputers. The incidents have already erased nearly 9 percent of Yandex share value and raised concerns over future capital expenditure, client retention in Yandex Cloud and potential sanctions complications for overseas expansion. Experts emphasize that the attacks have moved from isolated technical failures to a systemic business-continuity and investment-risk issue.
