A Yandex data center has been hit by a drone strike in Russia.

As reported by Kyiv Independent, the data center in question was the Yandex DC Sasovo, located in Sasovo, Ryazan Oblast, as identified by Ukrainian and Russian OSINT specialists Exilenova+ and ASTRA, and is Yandex's largest data center facility.

Yandex Cloud's status dashboard currently notes that it is suffering from a power outage at its ru-central-b availability zone. Disruptions began at 1:31am local time and are ongoing.

The data center is located at the Sasta production complex, which includes machinery and assembly workshops, R&D facilities, a foundry, and serves the Russian defence industry, among others.

Yandex said that the strike caused a fire at the data center, forcing it to cease operations.

This is the first major data center to be taken down in Russia during the conflict with Ukraine, but several data centers in Ukraine have been struck throughout, including multiple in just the last few weeks.

Facilities operated by Parkovyi Data Center, MiroHost, Datagroup, Vodafone Ukraine, De Novo, Cosmonova, Omega Telecom, and Ukrtelecom have all suffered damage from drones, though it is not known whether these data centers are all separate locations, or whether any of the companies were using shared facilities.

Yandex currently operates five large data centers in Russia located in Vladimir, Sasovo, Ivanteevka, Mytishchi, and in Kaluga Oblast around 200 miles (322 kms) south of Moscow. In April 2025, the company's Moscow cloud region suffered an outage after an incident with the supporting substation.

Yandex – which has been referred to colloquially as "Russia's Google" – was previously owned by a holding company based in the Netherlands, but separated its European and Russian operations, fully divesting Yandex from the company in February 2024 as part of a strategic move following the outbreak of the war in Ukraine. The European company is now known as Nebius, a neocloud.
