Repeated cable cuts expose submarine-network resilience risks
The Matsu Islands’ submarine cables were cut 27 times from 2018 to 2022, followed by four major outages from 2023 to 2025. The account points to the physical vulnerabilities and resilience challenges behind critical network links.
- What
- The Matsu Islands connect to Taiwan by submarine cables vulnerable to ship anchors and fishing equipment; they were cut 27 times from 2018 to 2022.
- How
- The global subsea network spans an estimated 1.5 million kilometres across 607 systems, and satellites could not replace it in a catastrophic outage.
- Why it matters
- Resilient network design must account for accidental, geological and deliberate cable damage that could leave communities isolated.
