Summary
Taiwan has activated backup communication systems for Dongyin, its northernmost island, after an undersea cable was damaged due to poor weather conditions shifting shipwreck debris. This incident has raised concerns about the vulnerability of undersea cables linking Taiwan to its outlying islands, particularly given past accusations against Chinese vessels for causing similar disruptions. The cable connecting Dongyin to Beigan, part of the Matsu islands, is currently being repaired by Chunghwa Telecom, with completion expected by the end of July, weather permitting. Meanwhile, mobile phone and internet services are functioning normally, though cable television services are down and some internet services may experience delays. Dongyin, which has a population of around 1,500 and a significant military presence, relies heavily on these communications for connectivity. In 2023, two undersea cables were cut, allegedly by Chinese ships, although no evidence of deliberate tampering was found. Taiwan has since been enhancing its communication resilience, including trials with low-Earth-orbit satellites. Key Points: • Taiwan activated backup communications for Dongyin after an undersea cable break. • The incident was caused by poor weather shifting shipwreck debris onto the cable. • Repairs are expected to be completed by the end of July, depending on weather conditions.
