Overview
- Yandex said late Sunday that a data center in Vladimir region was damaged by drone strikes, its work stopped, and Yandex Cloud moved into emergency mode with two availability zones unavailable.
- Users and businesses reported outages to taxi, payment and food‑delivery apps as well as internal courier and support tools across multiple Russian regions and in some foreign markets where Yandex operates.
- Vladimir's governor reported that two power substations serving about 5,000 people were cut, nearby residents were evacuated, power was later restored to roughly 80 percent, and no casualties were reported.
- The Russian Ministry of Defense said air defenses shot down 479 Ukrainian drones during the night, while Yandex and multiple news outlets attribute the data‑center hits to Ukrainian drone activity.
- Experts note Yandex runs six Russian data centers and warn that repeated strikes on the remaining sites could cause long‑term loss of the company’s domestic cloud infrastructure because centers are costly and slow to build.
