United24 Media reports that the facility is located in Grabtsevo industrial park and was designed to be the largest Yandex data center in all of Russia. It only entered service in the second half of 2023, lasting three years before this incident.
The Kaluga data center is a sprawling complex that covers around 1.4 million square feet (130,000 square meters). It's so vast that its 63-megawatt power capacity is around 50% higher than some other data centers owned by Yandex. With more than 3,800 server racks, it's perhaps easy to see why it became a target for Ukraine's drone operators. If, of course, the facility was the intended target for the attack — something yet to be confirmed.
As for what all those server racks actually do, it's reported that Yandex's internal services are housed at the facility. It was ultimately built to allow Yandex to expand its cloud offering.
It's as yet unclear how this drone strike is affecting everyday Russians, but the previous Sasovo strike also impacted Yandex Cloud. At the time, users reported problems with Yandex Mail, Disk, Documents, Pay, and Market despite Yandex claiming that key services remained up and running.
