Yandex Says Second Data Centre Hit by Drone Attack in Russia
Yandex said on October 9 that several modules at its data centre in Russia’s Kaluga region had been completely disabled by a drone attack, the second reported strike on a Yandex facility in two days. The company said some services may be disrupted and that no one was injured; Reuters did not independently verify the attack or assign responsibility for it.
PUBLIC RECORD / 01
The report confirms a second reported disruption at Yandex infrastructure, but leaves responsibility for the Kaluga attack unresolved and provides no basis for technical or procurement conclusions. New Ark commentary should remain limited to the project-level observation that critical digital infrastructure can face physical disruption; it should not turn the report into a product claim.
