The Russian Army Strikes at Ukraine's Data Centers and Moves the War into the Realm of Everyday Communication

Four dead in a business center in Kyiv and a temporary power outage affecting approximately 100,000 households — this is not just another episode in the missile-drone campaign. At the end of September 2026, Russian strikes on data centers and internet providers for the first time in a long while made civilian digital infrastructure an independent operational target. Moscow claims it targeted facilities used by Ukrainian military intelligence; Kyiv responds that these are systems on which alerts for missiles, banks, payments, transportation, and government services depend (BBC, September 26, 2026). The main meaning of this new phase of the war lies in this difference in wording.

From Energy War to War of Accessibility

Strikes on power plants have pursued a clear goal for several years — to deprive industry and the population of energy. The attacks on September 24-25 add another layer: to deprive the country of the ability to quickly exchange data even when electricity is still available. According to The Guardian, in Kyiv and the surrounding area, internet outages affected about 100,000 households after the strikes on Wednesday and Thursday, and on Friday, a drone hit the office of Datagroup, one of the largest communication operators. BBC lists among the affected facilities also New-Telco, United DC, Kyivstar, and Parkovyi. Datagroup's services, according to the company, continued to operate through backup sites, but the very fact of transferring data abroad shows the cost of the attack.

The military effect here is not measured by the number of destroyed servers. It is measured by delay. If an alert about an attack, an order to energy workers, or a payment operation is delayed by minutes, the decentralized network begins to lose not only bandwidth but also user trust. For the army, this means possible gaps between observation, decision-making, and target defeat; for the civilian administration — the inability to maintain a normal rhythm of life. In Soviet military theory, command of troops was a separate object of fire impact. Today, its civilian counterpart is cloud services, communication nodes, and data processing centers.

Why the Ukrainian Network is Holding Up for Now

The paradox is that Ukraine is vulnerable precisely because its digital infrastructure has become an important part of the state's resilience, but at the same time, it is less fragile than centralized systems of the Soviet type. The Ukrainian internet is relatively decentralized: operators use backup power, alternative routes, and sites abroad. Therefore, one successful strike does not automatically turn into a nationwide blackout. A representative of Ukrainian defense technologies, Sergey Beskrestnov, acknowledged the possibility of local outages but stated that the country would not be left without internet access (BBC).

This does not mean that the Russian strategy has failed. It may be aimed not at an immediate paralysis but at accumulating costs before winter. Each damaged node requires repair, backup capacities become more expensive, insurance costs rise, and operators are forced to transfer more and more data abroad. The result is a gradual increase in the cost of communication and a decrease in economic productivity without the dramatic picture of a complete blackout. In this sense, an attack on a data center is similar to blowing up a bridge: it is not necessary to destroy the entire structure; it is enough to force traffic to take a costly detour.

Starlink and the Polish Episode Expand the Geography of the Front

Particular attention should be paid to the fire at the Starlink station in Polish Wola-Krobowska, which transmits traffic, including for Ukraine. The Polish prosecutor's office has launched an investigation, stating reasonable suspicion that the perpetrators may have acted on the instructions of Russian special services; Moscow has not commented on this (BBC). Evidence of final coordination is still lacking, so it is premature to connect the two episodes into a single operation. But the military logic is clear: if Ukrainian communication relies on distributed nodes, the pressure is transferred along the entire chain — from the Kyiv data center to the foreign satellite access station.

This also shows the limitations of the previous understanding of Starlink as an almost invulnerable backup channel. The satellite constellation may continue to operate, but ground terminals, connection stations, power supplies, and traffic routing remain physical objects. The Russian army has already attempted to influence Ukrainian management through electronic warfare and strikes on energy; now it is testing whether it can make the digital network pay for its distribution with constant emergency costs.

Strategic Conclusion for Moscow and Kyiv

For Moscow, this is an attractive campaign for three reasons. First, striking dual-use objects allows for a military justification even when the main damage is felt by civilian users. Second, the cost of a cheap or relatively cheap drone can impose significantly higher costs on the communication operator for backup. Third, strikes on "ordinary life," as expressed by Volodymyr Zelensky, create psychological pressure on society before the winter season. But there is also a limit: too noticeable an expansion of the target list strengthens Ukraine's argument about the intentional terrorization of the population and makes it easier for European capitals to justify new supplies and funding.

Kyiv now needs not only air defense around energy facilities but also a full-fledged defense of its digital rear. This includes distributed data centers, synchronous backups outside the affected area, autonomous power supplies, rapid exchanges between operators, and pre-tested modes of operation without external internet. Patriot systems destroy missiles but do not restore damaged databases. This is the unpleasant lesson of modern warfare: a server rack may have less symbolic value than a tank, but its loss sometimes has a greater impact on the state's ability to act.

The Russian campaign against Ukraine's digital infrastructure does not promise an immediate collapse. Its more realistic goal is to turn resilience into an expensive and constantly repaired service.

If Kyiv maintains redundancy, attacks will remain a costly tool of attrition rather than a way to shut down the country. However, if winter brings simultaneous pressure on energy, communication, and logistics, local failures will begin to accumulate into a systemic deficit of manageability. The Russian army thus moves the front to where it is usually not seen: in data routes, backup generators, and the citizen's right to receive messages on time.
