Ukrainian drones target Yandex data center, disrupt AI operations in Ukraine

Ukraine’s drone fleet struck a Yandex data centre in eastern Ukraine on Tuesday, knocking out several supercomputers that feed the company’s artificial‑intelligence training pipeline. The facility, located near the city of Luhansk, was hit by a swarm of loitering drones that burst the building’s cooling system and caused a power outage that shut down the high‑performance GPUs. Yandex’s spokesperson said the attack disrupted the training of its new language model, which had been running for weeks on the damaged hardware. The damage is expected to delay the rollout of the AI service for several months.

Yandex is Russia’s equivalent of Google, with a market share of over 50% in the country and a growing presence in Europe and Asia. Its AI work powers everything from search to voice assistants, and the company has been investing heavily in machine‑learning infrastructure to compete with Western firms. Targeting Yandex’s data centre is part of Kyiv’s broader strategy to cripple Russian technological capabilities and to signal that civilian infrastructure can be hit with precision air‑to‑ground weapons. The attack follows a series of drone strikes on Russian‑controlled telecom and power sites that have increased in frequency as the war drags on.

The drones used were low‑cost, commercially available systems adapted by Ukrainian forces for combat use. They were launched from a distance of about 20 kilometres and guided by a combination of GPS and manual control. The strike damaged four GPU racks and one cooling unit, wiping out an estimated 200 teraflops of compute power. Yandex said it will rebuild the centre in a phased manner, but the loss of data and the time required to retrain models will cost the company an estimated $5 million. Russian officials have not yet issued a formal response, but analysts predict that Moscow may retaliate by targeting Ukrainian cyber‑infrastructure or by increasing its own cyber‑operations against Kyiv’s data assets.

The incident underscores how the war is spilling into the digital domain, where AI training and data centres become legitimate military targets. If Yandex cannot recover its compute capacity quickly, Russian AI development could lag behind the West, potentially affecting everything from autonomous systems to national security analytics. Ukraine’s use of drones to hit high‑value tech sites may prompt a new wave of cyber‑defence measures from Moscow, while also encouraging other countries to rethink the protection of their own AI infrastructure. The next few weeks will show whether Kyiv can maintain pressure on Russian tech, and whether Yandex can resume its AI programme without a prolonged interruption.
