Taiwan briefly slows its mobile internet to text-only speed as part of defense drill

Taiwan recently conducted a high-stakes test of its national defense readiness, forcing a temporary slowdown of mobile internet speeds across seven major cities, including Taipei. This action was part of the annual Han Kuang military exercises, which are designed to prepare the island for a potential Chinese military invasion. During this 30-minute window, mobile networks were throttled to 256 Kbps, restricting users to basic text-based communication instead of the high-speed 5G data they usually access.

President Lai Ching-te addressed the public to acknowledge the disruption, emphasizing that these measures are vital for national security. The exercises marked a shift in how Taiwan handles urban resilience drills. Unlike previous years, where air raid simulations often took place without significantly affecting the flow of daily life, this year's phase demanded active cooperation from civilians and local government bodies.

Beyond the digital infrastructure tests, the Han Kuang drills involved realistic scenarios such as relocating hospital operations to underground bunkers and restricting movement at metro stations. The shift toward integrating civilians into these drills highlights a broader strategic pivot to ensure that both critical infrastructure and the population can function under extreme conditions. Tourists and residents were required to halt transit during the simulated air raids, providing a clear picture of how a real emergency might unfold.

These maneuvers occur amid escalating regional tensions. The Taiwanese Defense Ministry reports daily activity from Chinese warplanes and navy vessels in the surrounding area. By simulating the loss of high-bandwidth connectivity, Taiwan is testing the ability of its command systems and civilian population to coordinate effectively when traditional communication channels are compromised. As the drills conclude, the government remains focused on integrating these lessons into its broader defense planning to ensure the island stays prepared for ongoing regional challenges.
