Ukrainian attacks damage Yandex supercomputers, threaten Russia's AI capabilities

Recent Ukrainian operations targeted Yandex's data centres, igniting a blaze at the Sasovo site on October 8 and forcing the Vladimir centre to cease activity on October 11. Satellite imagery confirmed fire damage, and independent analysts reported that the Chervonenkis, Lyapunov and Galushkin supercomputers are seriously impaired and currently non-operational. Although a strike on Sberbank's Balakovo centre occurred on October 14, the Christofari and Christofari Neo machines, located at the Skolkovo facility, were not hit.

Russia's top supercomputers rely on U.S.-made AMD, Intel and NVIDIA components, which have become difficult to replace due to post-2022 export restrictions. This loss reduces the country's capacity to train large generative-AI models, a strategic priority that has already lagged behind the United States and China.
