Drone attacks on Russian data centers have exacerbated the existing infrastructure deficit. Yandex lost approximately 115 MW of capacity, while the market previously faced an unmet demand of 150–200 MW. The incidents impacted dozens of Yandex services and over ten tenant platforms, including CIAN and various corporate ERP systems.
In response, Yandex Cloud shifted to emergency operations and partnered with Selectel, K2Cloud, and VK Cloud to relocate client data. The attacks also threatened the Chervonenkis, Galushkin, and Lyapunov supercomputers, which account for 73% of Russia's total supercomputing power. Sber provides an additional 23% of the nation's capacity.
Restoring the infrastructure may cost hundreds of billions of rubles. For context, building a 20 MW data center with 2,000 racks costs about 12 ₽ billion, excluding servers. Engineering works for a 40 MW facility, similar to Yandex's Vladimir site, are estimated at 20 ₽–35 billion. ComNews estimates a full day of downtime for Yandex at 4 ₽ billion.
Recovery is hindered by supply chain and construction timelines. Replacing engineering equipment takes two to six months, while constructing a new data center building requires about 1.5 years. Replacing supercomputers under current sanctions could take up to two years. Operators now face increased costs for physical security, and clients are shifting toward multi-site infrastructure.
