Taiwan's military and government authorities deliberately slowed mobile internet services in northern and central regions during the Han Kuang live-fire exercise.

The simulation is designed to test how the military and civilian populations communicate when bandwidth becomes scarce during a potential conflict. By mimicking the digital disruptions that often accompany modern warfare, officials aim to identify vulnerabilities in the island's emergency communication infrastructure.

The Han Kuang exercise lasts 10 days [1]. Launched on a Wednesday, the drills include various scenarios simulating a Chinese assault on the island. As part of these operations, the government scheduled two separate bandwidth-restriction tests [1].

Each of these throttling tests lasted 30 minutes [1]. During these windows, users in the affected northern and central regions experienced slower data speeds. The government used these windows to evaluate the resilience of critical communication channels under stress.

This approach to military readiness reflects a shift toward "hybrid warfare" preparation. Rather than focusing solely on kinetic weapons, the exercises now integrate the disruption of digital services to prepare the public for a scenario where standard internet access is unavailable or unreliable.

Authorities said the tests help ensure that the military can maintain command and control, and citizens receive essential instructions despite limited connectivity. The exercises continue to evolve to match the capabilities of potential adversaries.

The integration of internet throttling into the Han Kuang exercises indicates that Taiwan views digital resilience as a core component of national defense. By simulating a 'grey zone' attack—where infrastructure is degraded without a full-scale invasion—Taiwan is preparing its society for the psychological and operational challenges of a communication blackout, acknowledging that modern conflict begins in the digital domain before it reaches the physical battlefield.
