A Ukrainian drone strike damaged a Yandex data center in Russia's Kaluga region, and the company said several modules were completely disabled, the Associated Press reported on October 9. AP also reported an earlier attack that took a Yandex site in Ryazan offline on Thursday. Source: Associated Press.

A digital infrastructure target
The Kaluga statement confirms damage to some equipment but does not quantify lost capacity, customer disruption or repair time. The two reported incidents show why data centers now sit within the wider infrastructure risk picture of long-range drone warfare. Their cooling, power and network systems can be vulnerable even if the main building remains standing.
The resilience question
Operators generally plan for hardware failure and power outages; deliberate physical attack adds a different contingency. Redundant sites, data replication and protected utility feeds can limit service interruption, but the benefit depends on where workloads and backup capacity actually reside.
What is still unknown
The public record does not identify the aircraft type, the precise damage mechanism or a full restoration schedule. AP attributed the Kaluga damage confirmation to Yandex and separately reported regional officials' accounts of broader drone activity. Further technical detail is needed before judging the lasting operational impact.
