  • •Ukrainian drone strikes in October hit key Russian data centers, impacting AI capabilities.
  • •Yandex confirmed a permanent loss of 2.84% of customer data due to the attacks.
  • •Russian companies are increasingly seeking data center capacity abroad to mitigate risks.

In October 2026, Ukrainian drone strikes targeted multiple Russian data centers, including those operated by Yandex and Sber, resulting in significant operational disruptions. Yandex reported a permanent loss of 2.84% of customer data from its cloud services due to critical damage and lack of backups. The strikes have prompted Russian companies to seek data center capacity abroad, particularly in Kazakhstan, as domestic resources are nearly 90% occupied. The Russian government is considering establishing AI data centers in 'friendly' countries to mitigate risks. The attacks have raised concerns about the future of Russia's AI ambitions, with infrastructure constraints already limiting growth. The Kremlin's push for AI development is now further hindered by these strikes and ongoing sanctions affecting technology imports.
