Vanuatu fiber optic cable outage

Vanuatu's internet connectivity is highly vulnerable due to reliance on a single undersea cable, ICN1, with outages often caused by natural disasters or infrastructure issues.Current and Historical OutagesVanuatu has experienced significant disruptions to its fiber optic connectivity, primarily due to the ICN1 undersea cable, which links the country to international networks. A major outage occurred following a magnitude 7.3 earthquake in December 2024, which damaged the cable landing station in Port Vila, cutting off backhaul connectivity to mobile network operators and forcing reliance on satellite internet for government and emergency communications . Previous incidents, such as a fire at the cable landing station, also temporarily disabled internet traffic, highlighting the country's single point of failure in digital infrastructure .Impact on ConnectivityDuring outages, mobile networks like Digicel and Vodafone Vanuatu experience intermittent service, and commercial internet access is severely limited. Satellite solutions, including Starlink and geostationary satellites, provide temporary relief but are generally reserved for critical services due to limited bandwidth and high operational costs . For the general population, internet-dependent services such as social media, entertainment, and non-essential communications are often disrupted.Measures to Improve ResilienceTo address these vulnerabilities, the Asian Development Bank (ADB) and Prima Limited have initiated the Tamtam submarine cable project, a 411-kilometer link connecting Port Vila to Lifou, New Caledonia. Scheduled for service in December 2027, this cable will complement the existing ICN1 connection, providing redundancy and improving disaster resilience. The project also incorporates SMART technology for environmental monitoring and early warning systems, enhancing both telecommunications reliability and natural hazard preparedness .Broader ContextVanuatu's dependence on a single undersea cable reflects a broader challenge in the Pacific region, where funding and logistical constraints make redundant digital infrastructure difficult to implement. Governments and international partners, including Australia and the United States, have recognized the strategic importance of investing in submarine cables to ensure connectivity and resilience against natural disasters . Until additional cables are operational, Vanuatu remains vulnerable to outages caused by earthquakes, fires, or other disruptions at the cable landing stations. In summary, while Vanuatu's fiber optic network is currently fragile, ongoing projects like the Tamtam cable aim to reduce the risk of future outages and strengthen the country's digital and disaster resilience .
