02Deep-Dive Technical Analysis
In February 2023, Taiwan-Matsu Submarine Cable No. 2 was severed by a Chinese fishing boat, followed by Cable No. 3 being cut by a Chinese freighter. The incident knocked out high-speed internet and mobile data for 50 days, forcing Chunghwa Telecom to activate backup microwave relays that provided only 10% of standard capacity.
03Vulnerability & Exploit Flow
Physical anchor drag cutting across shallow subsea cable corridors.
04Recommended Defense & Mitigation Protocol
Deep undersea cable burial (>3 meters), automated AIS exclusion warning buoys, and sovereign LEO satellite constellation backup.
05Security Impact & Geopolitical Consequence
Demonstrated how grey-zone maritime operations can isolate offshore islands and critical populations, spurring Taiwan's nationwide initiative to deploy non-geostationary satellite broadband backup terminals across 700 locations.
