Taiwan holds an annual drill simulating a Chinese attack, during which millions of people are told to shelter indoors as sirens sound across Taipei and surrounding areas. During the exercise on Thursday, mobile internet speeds drop for about 30 minutes, with many residents moving to locations such as underground parking areas, subway stations, shopping malls and offices.

The drill is part of Taiwan’s “Han Kuang” military exercise, which is designed to prepare for a potential Chinese invasion of the island of about 23 million people. China views Taiwan as part of its territory and has threatened to use force to annex it, while Taiwan rejects that claim. Across the outlets provided, the reporting focuses on the public impact of the drill—sheltering measures and temporary communications disruption—rather than detailing any specific military scenario outcomes.

While the articles differ mainly in wording and emphasis, they consistently describe the timing of the sirens, the approximate duration of the mobile speed slowdown, and the exercise’s purpose within Taiwan’s broader preparedness posture toward China.
