Taiwan to Throttle 4G/5G Mobile Data for Half an Hour During National Resilience Drills
What Happened — Taiwan’s National Communications Commission will deliberately reduce 4G and 5G mobile data speeds to roughly 1 % of normal capacity for a 30‑minute window in 14 northern and central cities during the upcoming Urban Resilience Exercises, which run alongside the annual Han Kuang military drills. Voice calls, SMS, emergency alerts and land‑line services will remain operational; fixed broadband and Wi‑Fi are unaffected.
Why It Matters for Compliance & Audit Readiness
- The drill tests the organization’s ability to maintain critical communications under severe service degradation – a scenario directly addressed by SOC 2 CC6.1 (System Operations) and CC7.2 (Business Continuity).
- Documenting the throttling exercise, the decision‑making process, and the fallback procedures provides continuous evidence that your control environment can withstand real‑world disruptions.
- Verisq’s Control Mapping capability lets you align these resilience activities with SOC 2 criteria and generate audit‑ready proof that your continuity controls are exercised and verified.
Who Is Affected — Telecommunications providers, mobile‑network operators, and any SaaS or cloud services that rely on cellular connectivity for end‑user access (e.g., field‑service apps, IoT platforms).
Recommended Actions
- Map the throttling drill to SOC 2 CC6.1 and CC7.2 controls; capture run‑books, communications, and post‑exercise reports as evidence.
- Validate that alternative channels (Wi‑Fi, land‑line, satellite) are documented in your Business Continuity Plan and that users are trained on fallback procedures.
- Incorporate the drill’s metrics (duration, affected bandwidth, user impact) into your continuous‑monitoring dashboard for audit readiness.

Technical Notes
- No vulnerability or malware is involved; the slowdown is a controlled, government‑mandated throttling of 4G/5G radio resources.
- Impacted services: video streaming, video calls, large file transfers; essential communications (voice, SMS, emergency alerts) remain functional.
- The exercise highlights the importance of layered communications architecture and pre‑approved contingency pathways.
