Ukraine’s strike on Yandex demonstrated the reflections of an asymmetric attrition strategy and the deep strike doctrine through the targeting of Yandex’s data centers, in a landscape where Russia is attempting to advance in Donbas with manpower, artillery fire, and guided bombs. The target was the systems that sustain superiority.
According to reports, Ukraine struck Yandex data centers in three regions of Russia and a critical data processing center belonging to Sberbank. The impact was quite extensive. The targeting of three of the six data centers affected approximately half of the company’s operational infrastructure. The outages spread to Yandex Cloud and Yandex Pay. E-commerce businesses were also affected. Businesses dependent on this infrastructure in the billing and logistics fields also experienced outages.
The facilities had significant capacity. The struck facilities housed three supercomputers that Yandex used to train its large language models and artificial intelligence algorithms: – AMD Epyc processors – Nvidia A100 graphics accelerators
This replacement may not be easy. Due to sanctions and supply restrictions, rebuilding and replacing these systems could require time and resources for Russia.
The attacks show that the approach of keeping data within the country and maintaining centralized control creates new vulnerabilities when critical capacity is concentrated in specific facilities. The centralized structure becomes fragile. Ukraine’s distribution of its critical data across international cloud infrastructures, by contrast, offers a different resilience approach against this picture.
Why it matters
These attacks show that a class of targets has entered the war—one that reaches beyond the front line and directly strikes daily life and the economy: payment systems, cloud services, and businesses dependent on electronic commerce faced simultaneous outages. The most lasting consequence, however, emerges in artificial intelligence training capacity; for Russia, which will struggle to replace this hardware due to sanctions and supply restrictions, the loss means a cumulative setback rather than a short-term disruption. The development also leaves open a question about data sovereignty policies: the approach of keeping data within the country and maintaining centralized control produces fragility rather than security when critical capacity is concentrated in a few facilities. Compared with Ukraine’s distribution of its critical data across international cloud infrastructures, this picture makes visible how the two sides’ digital resilience choices play out on the ground.
