Ukrainian drones strike Yandex data hubs in widening technology campaign

Ukrainian drone attacks partly disabled a Yandex AI data centre in Russia's Kaluga region, the company said. A previous strike shut down a major data hub in Sasovo, Ryazan, where two of Yandex's three supercomputers for AI development are located. Yandex said the strikes hit the core of its operations and that staff are working to keep services running, as Ukraine expands its targeting of Russian technology infrastructure.
