Introduction

Yandex, Russia's dominant tech giant often dubbed 'Russia's Google', is facing service disruptions after Ukrainian drone strikes hit two of its data centres. The attacks underscore how the conflict is extending into critical digital infrastructure used by millions.

What Happened

According to company statements, Ukrainian drones targeted Yandex's facilities in Sasovo and Kaluga within the last 48 hours. The Sasovo centre, which houses two of the three supercomputers used to develop Yandex's AI models, was reported seriously damaged, with operations completely suspended. A separate strike on the Kaluga data centre, located southwest of Moscow, took part of its infrastructure offline. Yandex confirmed no employees were injured, though the regional governor in Kaluga reported nine people hurt in the drone attack on local infrastructure. The company acknowledged that some AI chatbot functions and smart home device services are currently affected, and that full restoration timelines remain uncertain.

Why This Matters

As 'Russia's Google', Yandex underpins daily digital life for millions through its search engine, food-ordering platform, and ride-hailing app. The outages highlight how infrastructure strikes are reshaping tech accessibility in the region. With the Kaluga centre described as one of Russia's largest, spanning 130,000 square metres and powering the equivalent of 220,000 UK households, the disruption has ripple effects across the country's digital economy. The attacks also reflect a broader pattern of infrastructure targeting, as both sides escalate strikes on data and energy facilities, potentially forcing resource reallocation from economic to repair efforts.

Key Takeaways

  • Yandex confirmed damage to its Sasovo and Kaluga data centres following drone strikes within two days.
  • The Sasovo facility hosts critical AI supercomputers; status of those processors remains unclear.
  • Yandex's Kaluga centre is one of Russia's largest, with power consumption equivalent to 220,000 UK homes.
  • No Yandex staff were injured, but nine local residents were hurt in the Kaluga drone attack.
  • Some AI chatbot and smart home services are temporarily offline; full restoration timeline is uncertain.
  • Ukraine's defence ministry said the strikes could compel Russia to redirect resources toward repairs.
  • The incident fits a wider escalation of infrastructure attacks ahead of winter, with both sides exchanging accusations of civilian targeting.

Conclusion

The latest strikes on Yandex data centres illustrate how the conflict's reach now extends into core digital infrastructure, affecting millions of daily users. As the company works to restore services, the situation underscores the fragility of concentrated tech ecosystems during geopolitical crises. Observers will be watching closely to see whether further disruptions emerge and how quickly Yandex can rebuild its operational capacity.
