APCN-2 break about 58 km off Tamsui, Taiwan

APCN-2 broke about 58 km from the Shalun landing station in Tamsui, Taiwan, on 22 September 2026, according to Taiwan's Ministry of Digital Affairs. Chunghwa Telecom, one of the cable's owners, confirmed the fault and moved its traffic to other international cables. Instead of a repair date, the ministry says APCN-2 is expected to be decommissioned on 31 December 2026.
