Ukraine: Civilian Communication Networks Under Infrastructure Attack
Russia's invasion of Ukraine in February 2022 created one of the most extensively documented cases of communication infrastructure under deliberate attack. Russian forces systematically targeted cellular towers, fiber routes, power infrastructure, and internet exchange points. The Ukrainian response — combining commercial satellite internet, civilian mesh networks, and — has provided important lessons for resilience planning worldwide.
Starlink Deployment
SpaceX began delivering terminals to Ukraine within days of the invasion, eventually providing tens of thousands of terminals. Starlink became critical infrastructure for military communication and coordination, government operations, civilian internet access in areas where terrestrial infrastructure was destroyed, hospital connectivity, and journalism.

- Terminals continued operating where all terrestrial infrastructure was destroyed
- Low-earth orbit constellation resilient to infrastructure attacks that would take out ground-based systems
- Rapid deployment — tens of thousands of terminals delivered within weeks
- SpaceX restricted service in certain areas to prevent offensive military use — a commercial provider can throttle or cut service
- Terminals require power, which Russia deliberately targeted via grid attacks
- Not available in all regions; coverage gaps existed throughout the conflict
Civilian Mesh Networks
Ukrainian civilian technology communities rapidly deployed mesh networks in areas where cellular infrastructure was destroyed. The Kyiv-based tech community, with support from international organizations, deployed networks in areas without cellular coverage, WiFi mesh networks in neighborhoods where power was available but cellular was not, and networks extending radio coverage in damaged areas.

Amateur Radio
The situation with in Ukraine was complicated. President Zelensky's February 24 state of emergency decree included a ban on amateur radio transmissions — partly to prevent Russian forces from using civilian signals for targeting. In practice, enforcement varied significantly by region: by late March 2022, radio operators in most oblasts (Kyiv, Lviv, Kharkiv, and others) confirmed no active ban was in place locally. Some operators engaged in civil defense activities, including monitoring enemy communications. See radio technology comparison →
Lessons
Commercial services are not reliable in geopolitical conflicts.
Starlink's partial service restrictions demonstrate that commercial satellite services are subject to provider decisions. Resilient communication requires options that are not controlled by a single commercial entity.
Layered redundancy is essential under deliberate attack.
No single technology survived all attack scenarios. Communities with multiple independent communication paths — Starlink + mesh + radio — maintained communication when any single system was disrupted.
Pre-existing community networks activated faster.
Communities with pre-existing mesh networks and communication plans activated faster and more effectively than those starting from scratch after the invasion began.
Power resilience is inseparable from communication resilience.
Russian attacks on the Ukrainian power grid directly degraded communication capability. Solar-powered nodes and battery-backed equipment maintained communication during outages.
Decentralized networks are harder to attack.
Mesh networks with no central point of failure proved more resilient than hub-and-spoke architectures. Destroying one node didn't take down the network.
In conflict zones, transmitting carries physical risk.
Amateur radio and other RF transmissions can reveal operator locations to adversaries with direction-finding equipment. Ukraine's ban was partly about protecting operators, not just operational security.
