The War Moves to the Cloud, and the Cloud Cannot Hide

In the fifth year of a war that has already reshaped the vocabulary of modern conflict, a new kind of target has emerged—not a bridge, not a power plant, not a barracks, but the quiet buildings where the digital life of nations is stored. Servers have become a frontline, and the hum of cooling fans has become a sound of vulnerability.

Over the past week, Ukrainian drones struck three major data centers operated by Yandex, often called Russia's Google, in the towns of Sasovo, Kaluga, and Vladimir. A fourth attack targeted a data center used by Sberbank, Russia's largest bank. The strikes followed Russian attacks on Ukrainian data centers and telecommunications sites, and President Volodymyr Zelenskyy described the operation as a direct response: "Ukrainians wanted to show Russians that two can play this game," a senior official familiar with the operation told Politico.

The consequences in Russia were immediate and visible. Yandex's cloud platform, which serves more than 50,000 businesses, entered "limited mode." Users could not order food or taxis, download files from cloud accounts, or transfer money through Yandex Pay. The mapping app blurred street-level images. The website of Pulkovo, the airport serving St. Petersburg, went offline. Service disruptions spread to Kazakhstan, Uzbekistan, and Belarus, where Yandex holds a dominant market share.

What makes Russia particularly vulnerable is a decade of policy designed to reduce reliance on foreign technology. Legislation passed in 2014 required companies to store personal data on servers inside the country. Cross-border sanctions made it difficult to rely on internet services hosted abroad. The result was a centralized digital ecosystem—and a single point of failure. "Russia is probably more vulnerable to data center warfare than Ukraine is," said Vili Lehdonvirta, a technology policy professor at Aalto University.

The cost of rebuilding will be steep. Data centers require specialized hardware, much of which must be imported and is complicated by sanctions and global demand. "Obtaining a large amount of equipment to replace what was destroyed is not going to be easy," said Oleg Shakirov, a cyber policy researcher.

Experts also warn that normalizing strikes on digital infrastructure could set a dangerous precedent. "These strikes likely breach International Humanitarian Law," said Joseph Jarnecki of the Royal United Services Institute, "and it's a big risk when global populations increasingly rely on digital services". A senior NATO official, speaking anonymously, confirmed that the alliance is already factoring data center vulnerability into its planning: "We would get it in a fight."

The Kremlin acknowledged the difficulties this week. "It is too early to talk about financial losses," said spokesperson Dmitry Peskov. "Yes, it is currently facing difficulties, and of course, this issue is being discussed within the government". For now, the restoration work continues around the clock, and the question of what else might be targeted remains open.
