“Several modules of the Yandex data center in Kaluga have been completely taken out of operation as a result of a UAV attack, the company reports,” TASS said.
The Kaluga facility, located in the Grabtsevo industrial park, was designed as Yandex’s largest data center in Russia. Construction began in 2022, with the site entering operation in the second half of 2023.
The complex covers roughly 130,000 square meters and has a planned power capacity of 63 megawatts—about 50% greater than some of Yandex’s other major data centers. It can accommodate more than 3,800 server racks, each designed for loads of up to 15 kilowatts.
The facility supports Yandex’s internal services and was also built to expand Yandex Cloud, including the company’s fourth availability zone.
Earlier, satellite images revealed the extent of the damage to a data center operated by Russian technology company Yandex in Sasovo, Russia’s Ryazan region, after a Ukrainian drone strike.
