Ukraine’s Drone Campaign Hits Another Yandex Data Centre in Russia
Data centres have become essential infrastructure for modern economies. They support cloud computing, digital payments, business applications, artificial intelligence and the online services people use every day.
A recent attack on a data centre operated by Russian technology company Yandex has highlighted the vulnerability of this infrastructure during armed conflict.
Reuters reported on October 9 that Ukraine had targeted a second major Yandex data centre, with the latest strike affecting a facility in Russia’s Kaluga region. The report follows an earlier attack on the company’s data infrastructure in Sasovo. Read Reuters’ report.
Why data centres matter
Data centres are specialised facilities housing servers, storage systems and networking equipment. They provide the computing capacity behind services ranging from online search and navigation to cloud platforms and AI development.
When a facility is disrupted, the effects can extend beyond the company that owns it. Businesses relying on hosted databases, applications and cloud infrastructure may also experience interruptions.
Yandex, often described as Russia’s equivalent of Google because of its broad digital services, operates infrastructure supporting a range of online products.
The company has multiple data centres, which can help it redirect workloads when one location becomes unavailable. However, redundancy cannot eliminate every risk, particularly when multiple facilities or interconnected systems are affected.
AI infrastructure adds another dimension
Data centres are becoming increasingly important as companies invest in artificial intelligence.
Training and operating advanced AI models requires substantial computing capacity, specialised hardware, reliable electricity and high-speed networking. Interruptions can therefore affect not only consumer services but also the development and operation of AI systems.
The Reuters report said an earlier strike disrupted two of Yandex’s three supercomputers used for AI model development. The latest incident adds to concerns about the resilience of digital infrastructure in a conflict environment.
The events also demonstrate that technology infrastructure can become entangled in wider geopolitical disputes, even though many of the services it supports are used for ordinary commercial purposes.
Resilience is more than having backup servers
Organisations often design their systems to withstand individual equipment failures. But large-scale disruptions require broader planning.
Companies may need geographically separated backup facilities, replicated databases, tested recovery procedures and alternative network routes. They also need to determine how quickly critical services can be restored if a major location becomes unavailable.
Physical security is another consideration. Data centres depend on buildings, power systems, cooling equipment, fibre connections and other infrastructure that cannot be protected through software alone.
For cloud customers, the incidents are a reminder to understand how providers distribute workloads and whether critical data is replicated across genuinely separate locations.
A growing strategic concern
The world’s dependence on digital services means that data centres are no longer simply technical facilities hidden behind the internet. They are part of the infrastructure supporting economic activity, public services and national security.
As AI investment expands, the strategic importance of large computing facilities is likely to increase further.
For technology companies, resilience planning must account for more than cyberattacks and routine hardware failures. Physical threats and regional instability can also disrupt the systems on which customers depend.
The bottom line: A data centre outage can become a much wider digital disruption. Protecting critical technology infrastructure requires both cybersecurity and physical resilience.
