Ukrainian drones hit two Yandex data centres in Russia in two days

Two Russian data centres operated by Yandex have been struck by Ukrainian drones in as many days, the company says. Several modules at its Kaluga facility were out of service after Friday’s attack. Another Yandex centre at Sasovo, in Ryazan region, was knocked offline on Thursday.

A new target in a long-range campaign

The attacks extend Ukraine’s cross-border campaign into digital infrastructure that supports businesses and consumers. Ukrainian President Volodymyr Zelenskyy confirmed Kyiv’s role in the Kaluga strike and linked it to Russian attacks on Ukrainian data centres. Drone maker Firepoint told Reuters its FP-1 aircraft were used; that account is attributed to the manufacturer.

What remains unclear

Yandex says it is assessing the damage and working to restore services, including helping cloud customers move data where necessary. The scale and duration of disruption have not been established. The company has not confirmed whether supercomputers at Sasovo were affected. There is no verified basis to claim a nationwide internet shutdown or stolen customer data.

Casualty reports need context

The Kaluga regional governor reported nine people injured in drone attacks across the region. Yandex said nobody was injured at its data-centre site. These statements concern different areas and do not contradict each other.
