Russia Intensifies Strikes on Ukraine Data Centers, Disrupting Internet in Kyiv Since Sept. 23
3 articles · Updated · Institute for the Study of War · Sep 29
Summary
Russian strikes have hit Kyiv data centers daily since Sept. 23, damaging multiple internet providers and causing widespread connectivity disruptions in the capital.
295 drones and decoys were launched overnight on Sept. 24-25, with Ukraine saying 267 were downed, as Moscow broadened attacks on telecommunications, energy, transport and other civilian infrastructure.
Ukrainian officials say the campaign is a targeted escalation aimed at the economy: outages have disrupted mobile air-raid alerts and could raise internet costs, though authorities see no damage to military or state communications.
A complete national blackout remains unlikely because Ukraine has a widely distributed network and many providers, but officials warn broader telecom disruptions could threaten banks, online payments, businesses and government services.
The digital strikes fit Russia's wider 2026 effort to hit ports, railways and industry after battlefield offensives fell short and Ukrainian forces made gains.
As Russia targets Ukraine’s data centers and telecoms, can stronger air defense and dispersed infrastructure keep the country connected and protected?
If Ukraine can build PAC-2 before PAC-3, does that change the military balance—or mainly signal a longer-term NATO-backed industrial shift?
Escalation in the Cloud: Russia’s September 2026 Attacks on Ukraine’s Data Centers and the Future of Hybrid Warfare
Overview
In September 2026, Russia launched a focused aerial campaign against Ukraine’s digital infrastructure, striking key data centers in Kyiv and causing internet outages for about 100,000 households. Despite the destruction of local facilities, most customers of major providers like MiroHost stayed online thanks to decentralized networks and international backups. As the battlefield stalemate deepened, Russia increased missile production and overwhelmed Ukraine’s air defenses, making physical attacks on data centers more effective than cyberattacks alone. Ukraine’s rapid emergency repairs and resilient network design prevented a nationwide blackout, while international legal experts began gathering evidence to pursue war crimes charges for these systematic strikes on civilian communications.
