Taiwan Tests Network Slowdown Drills for Civil Defense Readiness

Taiwan's "2026 City Resilience (Air Defense) Exercise" on August 10, 2026, included a novel simulation of mobile network slowdowns in central Taiwan. The drill, designed to test the government's response to communication constraints during major disasters or wartime, saw download speeds reduced to 256KB.

The exercise, coordinated by an inter-ministerial response center, verified the operational continuity of critical public services. Police, fire departments, and emergency medical services reported normal functioning throughout the simulation. Backup communication methods, including mobile base stations, low-orbit satellites, microwave, and radio systems, were activated and tested.

Government fixed-line networks, hospital networks, and Wi-Fi services remained operational. Essential civilian infrastructure such as water and electricity were unaffected. The drill concluded successfully at 3 p.m., with all systems returning to normal. Authorities emphasized that the exercise's purpose was not merely to test network speed reduction but to validate the resilience of command structures and essential services under extreme pressure.

Emergency call data from the central region showed no significant anomalies compared to the previous year, with 243 calls to 110, 6 video reports, and 5 SMS reports. Fire department call volumes were slightly higher than average but considered within normal ranges. The Ministry of Communications and National Communications Commission (NCC) will use the experience to refine procedures for a similar drill planned for northern Taiwan on August 13 and for future improvements to national communication resilience.

The drill's purpose is not to simply test 'slower internet,' but to actually verify whether the government command system, police, fire, and medical services, and essential public services can continue to operate when mobile communication resources are limited, and whether various backup communication mechanisms can be activated in a timely manner.
