Subsea cables are the backbone of the global digital economy, carrying over 99% of intercontinental data traffic. As trans-Pacific bandwidth demand continues to grow—tripling between 2019 and 2023—ensuring network resilience, security, and scalability is more critical than ever. The increasing dominance of content providers, geopolitical complexities, and supply chain disruptions have reshaped subsea connectivity dynamics.
Cable Vulnerabilities: A Growing Concern
Despite technological advancements, subsea cables remain highly vulnerable to external threats. The average cable lifespan is 25 years, but economic viability is often shorter due to the increasing demand for higher-capacity, lower-latency networks. Subsea cables are frequently damaged by human activity, including fishing, anchoring, and accidental cuts. Between 150–200 cable faults—breakage or other types of damage—occur each year, with nearly two-thirds caused by “external aggression,” typically from fishing and transport vessels. With demand for connectivity skyrocketing, cable resilience has become a priority for telecom operators and hyperscalers alike.
Cable repairs are an ongoing challenge due to the limited number of specialized repair vessels available worldwide. When a fault occurs, it can take weeks—sometimes months—to deploy a vessel, obtain the necessary permits, and conduct repairs, especially in politically sensitive regions like the South China Sea. Traditional pathways such as the South China Sea and the Strait of Malacca are becoming heavily congested, leading to concerns over repair delays and limited capacity.
The subsea industry faces a critical shortfall in repair vessels, leading to severe delays in cable repairs. Many cable cuts can take up to six months to repair, underscoring how bureaucratic delays, lack of available ships, and political instability contribute to prolonged outages.
Geopolitical Risks and Regulatory Bottlenecks
The geopolitical climate surrounding subsea cables has grown increasingly complex. Geopolitical issues, particularly rising tensions in regions like the South China Sea and Red Sea, have exposed the vulnerabilities associated with relying on these conventional routes. Governments, particularly in the U.S. and its allies, are advocating for cable routes that avoid Chinese territorial waters.
Regulatory approval processes in certain regions have become more stringent, adding delays to the deployment of new systems. Moreover, concerns over cybersecurity and potential espionage have led to stricter security protocols. Governments worldwide are implementing stricter cybersecurity measures to mitigate the risk of espionage and cyber threats targeting these critical infrastructures. While these policies enhance security, they also create additional bureaucratic delays that impact cable rollout and maintenance.
Telin’s Approach to Resiliency
Recognizing the pressing need for resilient subsea networks, Telin has strategically designed the Indonesia Cable Express (ICE) system to overcome traditional connectivity bottlenecks. The ICE cable project, seen as a game changer, aims to address these concerns by integrating advanced fault detection technology and establishing redundant pathways to minimize downtime in the event of cable failure.
By using alternative landing points in Indonesia, the ICE system provides enhanced resiliency, ensuring that global traffic remains uninterrupted even in the event of geopolitical tensions or cable damage. The project also incorporates AI-driven predictive maintenance, which helps detect potential failures before they occur, reducing the risk of prolonged downtime.
“Our waters provide a secure, low-latency alternative to congested areas, delivering latency reductions of up to 40 milliseconds,” said Budi Satria Dharma Purba, CEO of Telin.
The ICE project, spanning seven systems, introduces innovative solutions like new gateways in Manado, strategically connecting underserved regions in eastern Indonesia to global hubs in North Asia, North America, and beyond. By bypassing high-risk areas and reducing dependency on traditional routes, the ICE project is enhancing regional redundancy and setting a new standard for subsea connectivity.
Additionally, Indonesia is prioritizing investment in domestic marine maintenance infrastructure, ensuring faster response times for cable faults affecting regional and trans-Pacific networks. This investment is set to provide a crucial competitive advantage over alternative landing hubs.

The urgency of ensuring subsea network resiliency cannot be overstated. With growing threats from human activity, natural disasters, and geopolitical instability, the industry must prioritize alternative routes, faster repair mechanisms, and advanced monitoring systems. Telin’s commitment to resilient infrastructure through ICE and next-generation cable systems is shaping the future of global digital connectivity, ensuring uninterrupted access to critical data flows.
