發生了什麼
2026年8月10日14:30至15:00，臺灣中部七個縣市 — 臺中市、嘉義市，以及苗栗、彰化、南投、雲林與嘉義縣 — 的行動數據速度遭到刻意降低，作為漢光演習的民間部分。這是臺灣首次行動網路限速演練。國家通訊傳播委員會約提前三週公布範圍，包括不受限速影響的服務：語音通話、撥打110與119的緊急電話、簡訊與災防告警細胞廣播，以及固網寬頻、經由固網寬頻提供的Wi-Fi、市內電話，和軍事及其他專用網路。依官方說明，此演練模擬的是緊急網路措施 — 壅塞、災時漫遊與流量優先排序 — 所造成的頻寬下降；主管機關表示這並非斷網。通訊社報導指出，行動網頁流量的上限為256 Kbps，另有描述稱約為一般4G與5G容量的百分之一。
The significant thing is not that connectivity was degraded but that the degradation was scoped, announced and bounded — and that the boundary was drawn around exactly the services a population needs in an emergency. A state that can publish, in advance, which of its own communications it is willing to give up and which it is not, is describing a continuity doctrine rather than running a stunt. This module's standing position is that resilience is the trackable part of deterrence because programmes are either delivered or not; this is delivery, and it is the first of its kind. What the exercise does NOT do is reproduce a wartime cause. Throttling reproduces a condition — degraded mobile data — through an administrative mechanism. Infrastructure damage, power disruption, cyber intrusion, electronic interference and network saturation are separate hypothetical mechanisms that could produce a comparable condition in a conflict, and none of them was simulated, tested or observed here. Vigil makes no assessment of how the public or agencies performed.
