Two Yandex data centers in Russia were struck by drones in two separate incidents over two days, resulting in damage to the Kaluga facility. The second attack occurred on Oct. 8, causing several modules within the Kaluga data center to lose operations. The company had previously identified this Kaluga facility as its most powerful data center in Russia.
Yandex's press service confirmed that specialists are still evaluating the damage extent, while specific affected systems and potential restoration of disabled modules remain undisclosed. No human casualties were reported in either incident. The Kaluga data center, under construction since 2022, was designed to house over 3,800 server racks and had a design capacity of 63 MW.
The first phase of the facility became operational in December 2023. The power grid connection of Yandex's largest data center was confirmed in October 2024, with a maximum power consumption of 49 MW. The drone strikes disrupted various Russian internet services, including Yandex's digital platforms, causing widespread outages across the country.
