Taiwan's National Communications Commission (NCC) said Monday that mobile data services would be throttled for half an hour in 14 cities and counties in northern and central Taiwan during the Urban Resilience Exercises, held alongside the annual Han Kuang military drills in mid-August. Voice calls, text messages, emergency alerts and calls to emergency services will continue to function. Fixed broadband, WiFi, landline telephone services, military communications and other dedicated networks will continue to operate normally. The drill is part of Taiwan's annual Urban Resilience Exercises, which are integrated with the Han Kuang operation. The exercise comes as Taiwan places greater emphasis on resilience against both military conflict — presumably with China — and natural disasters such as typhoons and earthquakes.
