Current Status & Impact<\/strong><\/p>\n\n\n\n

Vietnam is experiencing a major disruption to its international internet connectivity due to simultaneous faults on four out of its six primary subsea cable systems. The outages have knocked out approximately 30% of Vietnam’s total international internet capacity. While domestic internet traffic remains stable, users face slower speeds, high latency, and intermittent connection drops during peak evening hours when accessing overseas-hosted services, including social media platforms, international streaming, and global gaming servers.<\/p>\n\n\n\n

Incident Timelines & Repair Schedules<\/strong><\/p>\n\n\n\n

Direct internet providers like VNPT and Viettel are actively rerouting data through land-based networks (terrestrial cables running through China and Southeast Asia) and the country’s two remaining functional subsea lines to mitigate the severe bandwidth deficit. [3, 5] <\/p>\n\n\n\n

Subsea Cable System<\/td>Outage Start \/ Background<\/td>Repair Status & Expected Timeline<\/td><\/tr>
AAE-1 (Asia-Africa-Europe 1)<\/td>February 2026; suffered an un-repaired fault on its S1.H2 segment, compounded by a fresh rupture in late August.<\/td>Repair work is tentatively scheduled to begin late September 2026, heavily dependent on specialized vessel availability and weather conditions.<\/td><\/tr>
SJC2 (Southeast Asia-Japan 2)<\/td>August 25, 2026; suffered a sudden fault on the S4 segment near Chung Hom Kok, Hong Kong.<\/td>No specific repair timetable has been released by the international cable operator.<\/td><\/tr>
AAG (Asia-America Gateway)<\/td>Ongoing from mid-2026; the line was already down for unresolved, historical issues when the new wave of faults hit.<\/td>Maintenance operations are expected to officially commence early September 2026.<\/td><\/tr>
TGN-IA (Tata TGN Intra-Asia)<\/td>Late August 2026; became the fourth system flagged as actively impaired.<\/td>Repair operations are slated to begin in early September 2026.<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n

Next Steps & Strategic Outlook<\/strong><\/p>\n\n\n\n

The overlapping nature of these faults underscores long-standing vulnerabilities in the country’s data infrastructure, which averages 10 subsea incidents a year. In response, the Vietnamese government is prioritising its Digital Infrastructure Master Plan, aiming to deploy over 10 new subsea cable systems across distributed coastal landing stations by 2030 to establish long-term internet resilience.<\/p>\n","protected":false},"excerpt":{"rendered":"
