Taiwan-Penghu Subsea Cable No.3 Completely Broken: The Ministry of Digital Affairs Deploys Backup Cable and Speeds up Repair Work
The Ministry of Digital Affairs (MODA) announced on February 25th that it had received a report from Chunghwa Telecom regarding a complete disconnection of the Taiwan-Penghu Subsea Cable No.3. Following standard procedures, Chunghwa Telecom immediately notified the Ocean Affairs Council and the Coast Guard Administration, requesting assistance in investigating the cause of the cable failure. To mitigate the potential impact of this disconnection, the Ministry directed Chunghwa Telecom to reroute communications traffic to other subsea cables, ensuring that communication between Taiwan, Penghu, and Kinmen remains unaffected. MODA also instructed Chunghwa Telecom to coordinate with subsea cable repair vessels to prioritize the repair of Taiwan-Penghu Subsea Cable No.3 as soon as possible.
According to MODA, the National Communications and Cyber Security Center (NCCSC) received a report from Chunghwa Telecom indicating that at 3:03 AM on February 25th, the Taiwan-Penghu Subsea Cable No.3, located 14.7 km off the coast of Beimen, Tainan, experienced a complete disconnection. To maintain stable communications for the Penghu and Kinmen regions, MODA confirmed that there are still active interconnections via Taiwan-Penghu Subsea Cable No.2, Penghu-Kinmen Subsea Cable No.3, and Taiwan-Kinmen Subsea Cable No.2. The ministry instructed Chunghwa Telecom to immediately reroute voice and internet traffic from the Taiwan-Penghu Subsea Cable No.3 to other available subsea cables. Additionally, MODA requested that Chunghwa Telecom coordinate with a subsea cable repair vessel that arrived in Kaohsiung on February 2nd, ensuring that after completing the repairs of the Taiwan-Matsu Subsea Cable No.3 and Taiwan-Matsu Subsea Cable No.2, it proceeds immediately to repair the Taiwan-Penghu Subsea Cable No.3. According to Chunghwa Telecom's latest update, the repairs for Taiwan-Matsu Subsea Cable No.3 and Taiwan-Matsu Subsea Cable No.2 are expected to be completed by the end of February and March, respectively, depending on sea conditions.
Also, MODA has requested the Executive Yuan to designate all 14 international subsea cables and 10 domestic subsea cables as Critical Infrastructure (CI). MODA will continue to uphold the principle of "backup and backup" to strengthen communication resilience for outlying islands, which includes deploying Non-Geostationary Satellite stations at key government locations, subsidizing telecom providers to expand microwave capacity, and investing in subsea cable infrastructure. By implementing diverse and redundant communication backup mechanisms, MODA aims to enhance overall network stability further to ensure uninterrupted government operations and public communication.
