Taiwan Simulates Internet Blackout in Large-Scale Civil Defense Drill

The Government of the Republic of China conducted a large-scale civil defense drill across 14 cities and counties in northern and central Taiwan to simulate a coordinated internet blackout. For the first time, authorities intentionally reduced internet speeds to disrupt data-heavy services, including mobile payments, video calls, and streaming, to test backup communication systems and public resilience.

The exercise responds to potential military threats from China, which claims Taiwan as its own territory. Officials are specifically concerned about the vulnerability of submarine cables to grey zone tactics. To mitigate these risks, the government is prioritizing the development of multiple communication layers, including low-Earth-orbit satellite services.

In a related move to strengthen infrastructure, the Legislature of Taiwan recently approved amendments that could allow Starlink to enter the local market. This policy shift draws on lessons from the conflict in Ukraine to ensure communication continuity during a crisis.
