Russia’s latest strikes on Ukraine have highlighted a battlefield that is less visible than tanks, missiles and trenches but increasingly important to modern warfare: the digital infrastructure that keeps a country connected.
On September 27, Russia struck the headquarters of Kyivstar, Ukraine’s largest mobile operator, in Kyiv. The company confirmed that its head office was hit and said there were no casualties among its employees. On the same day, Russia’s Defense Ministry said it had struck a data center belonging to Vodafone Ukraine, the country’s second-largest mobile network operator. Vodafone had not publicly commented on that claim at the time of the Reuters report.
Ukrainian President Volodymyr Zelenskyy also said a data center in Kyiv was struck twice during the morning, with two children and an adult injured. Reuters could not independently verify all of the Russian military’s claims about the facilities it said were targeted.
The significance of the attacks, however, goes beyond the damage to individual buildings. They raise a much larger question: Can Ukraine keep its digital nervous system functioning while Russia increasingly puts communications infrastructure under pressure?
The War Is Moving Into the Network
For most people, a mobile network is something they notice only when it stops working. In wartime, however, connectivity can become as important as electricity.
Phones are used to communicate with family members, coordinate emergency responses, receive government alerts and access essential services. Internet providers connect homes, businesses and public institutions. Data centers support the digital systems behind those services.
That makes physical infrastructure supporting communications an increasingly important part of Ukraine’s wartime resilience.
Ukraine’s Digital Ministry said Russian attacks on data centers belonging to internet providers during the previous week had caused outages affecting about 100,000 households in Kyiv and the surrounding region. Ukrainian Foreign Minister Andrii Sybiha said major data centers were being targeted in an attempt to disrupt the flow of information and stressed that rapid warnings about missile and drone threats can save lives.
The message is clear: damaging a server facility does not merely mean damaging computers. It can affect the information moving through an entire system.
Kyivstar Is More Than a Phone Company
The choice of Kyivstar’s headquarters is significant because of the company’s scale.
Kyivstar describes itself as Ukraine’s leading digital operator. As of the end of 2025, it had more than 22.4 million mobile customers and more than 1.2 million fixed-line home internet customers. The company also operates digital services involving cloud technology, cybersecurity, digital television, health services and other business solutions.
That makes the company’s infrastructure part of a much larger digital ecosystem.
Kyivstar has also spent heavily on rebuilding and strengthening its network since Russia’s full-scale invasion. The company said its investments in infrastructure restoration, modernization and digital capacity had reached approximately $913 million since the beginning of the war. It also reported restoring nearly 700 damaged network sites since the invasion began.
That history illustrates an important feature of the conflict: Ukraine is not simply trying to prevent infrastructure from being destroyed. It is repeatedly rebuilding it while the war continues.
Data Centers Are Becoming Strategic Targets
The recent attacks suggest that Russia’s campaign is extending beyond traditional communications towers.
Data centers are physical facilities filled with servers, networking equipment, power systems and cooling infrastructure. They provide the backbone for digital services that people may never realize depend on them.
Destroying or disabling such facilities can therefore have effects that spread beyond the immediate blast area.
Reports from Ukraine during the past week described damage to several data-center facilities and internet infrastructure. Ukrainian authorities said those attacks contributed to internet disruptions affecting approximately 100,000 households around Kyiv.
But it is important not to assume that every outage represents a permanent collapse of Ukraine’s digital network. Modern telecom systems are built with redundancy, alternative routing and backup infrastructure precisely because individual components can fail.
The real contest is therefore one of resilience: How quickly can Ukraine restore connectivity after each strike?
Why Redundancy Matters in Wartime
Think of Ukraine’s communications network as a road system.
If one bridge is destroyed, traffic can sometimes be redirected to another bridge. If several bridges are hit simultaneously, however, the alternatives become increasingly crowded and vulnerable.
Telecommunications networks face a similar challenge.
Companies can maintain backup systems, distribute equipment across multiple locations and use alternative routes for data. But redundancy costs money, requires planning and can eventually be overwhelmed if attacks become frequent enough.
Kyivstar’s own investment figures show how much effort has already gone into this resilience. During 2025, the company built more than 6,000 new base stations and upgraded more than 10,000 existing sites. It also said more than 10 network sites damaged by attacks were restored during that year.
The latest strike demonstrates why those investments remain necessary.
The Civilian Cost Can Be Larger Than the Building Damage
A damaged headquarters can be repaired. A destroyed server room can eventually be rebuilt.
The harder problem is what happens to people while those systems are unavailable.
For civilians living under frequent missile and drone attacks, access to timely information can be critical. Internet and mobile services may be needed to receive warnings, contact emergency services, check transport information, communicate with relatives or conduct basic financial and commercial activities.
That is why Ukraine has repeatedly emphasized the importance of maintaining communications during attacks.
At the same time, the reported injuries at a Kyiv data center show another reality. Digital infrastructure is not an abstract target floating somewhere in cyberspace. It exists inside physical buildings, often in urban areas, where workers and civilians can be exposed to the consequences of attacks.
Russia Says It Is Targeting Military-Related Infrastructure
Russia has described some of its strikes as attacks against infrastructure connected to Ukraine’s military.
On September 27, Russia’s Defense Ministry said its forces had struck communications centers and other infrastructure it considered linked to the Ukrainian military. Reuters noted that the claims could not be independently verified.
That distinction matters.
A telecommunications company can serve millions of civilians while also providing services that may be used by government institutions or military personnel. Establishing exactly what a particular facility was being used for requires evidence beyond the fact that it belongs to a communications company.
The latest reporting therefore supports a broader conclusion about the vulnerability of Ukraine’s digital infrastructure without proving that every facility struck was being used for military purposes.
Ukraine’s Digital Resilience Is Becoming a Strategic Asset
Ukraine has spent years adapting its infrastructure to survive the war.
Telecom operators have repaired damaged sites, expanded networks and invested in backup capacity. Businesses have also learned to operate under conditions where electricity, internet access and physical infrastructure can be disrupted.
That experience could become one of the country’s most important forms of resilience.
The objective is no longer simply to build the biggest or fastest network. It is to build one capable of recovering quickly when part of it is damaged.
In that sense, the latest attacks are testing more than concrete buildings and telecommunications equipment. They are testing the ability of a modern state to continue functioning when the physical foundations of its digital economy are repeatedly attacked.
The New Battlefield Has No Clear Front Line
The most important development may therefore be the gradual disappearance of the traditional boundary between physical and digital warfare.
A missile hitting a communications facility can create digital consequences. A cyberattack can disrupt physical services. A power outage can take data centers offline. And damage to one part of a network can create problems hundreds of miles away.
Ukraine’s experience demonstrates how interconnected these systems have become.
Russia’s latest attacks on Kyivstar, Vodafone-linked infrastructure and other data centers show that the country’s digital backbone is increasingly exposed to the same physical dangers as power stations, factories and transport infrastructure.
The central question is not simply how much infrastructure was destroyed on September 27.
It is whether Ukraine can keep rebuilding faster than the war can destroy.
That may ultimately determine whether these strikes produce temporary disruptions or a lasting impact on the country’s ability to communicate, operate businesses and maintain essential services during the conflict.
