Resilience Takes Center Stage at Submarine Cable Summit
During the recent International Submarine Cable Resilience Summit 2026 in Porto, Portugal, a defining theme emerged among infrastructure operators, regulators, financial institutions, and global organizations: resilience has evolved from a technical challenge into an economic imperative. For West Africa, this discussion is not purely academic; it has immediate and far-reaching implications. The region boasts a combined GDP exceeding $800 billion and is undergoing a significant digital transformation. The digital economy, encompassing fintech, e-commerce, digital services, and connectivity, is poised to contribute between $100 billion and $150 billion annually to economic activity, with expectations of robust growth. Digital platforms are increasingly playing a vital role in overcoming historical infrastructure shortcomings, boosting productivity, attracting investment, and generating jobs. However, this transformation is precariously built on a fragile foundation.
System Failures Highlight Vulnerabilities
In March 2024, a series of undersea cable failures along the West African coast exposed critical gaps within this fledgling digital economy. Connectivity faltered across multiple countries for hours and, in some instances, days. Banking systems experienced slowdowns, digital platforms crashed, and businesses reliant on cloud infrastructure were severely disrupted. This incident was not an isolated occurrence. According to the International Cable Protection Commission, most submarine cable failures globally stem from fishing activities, anchorage, or natural seabed shifts. However, what set West Africa’s situation apart was the unprecedented scale of the disruptions, with multiple cables sustaining damage simultaneously, leaving available bandwidth critically diminished and existing redundancies overwhelmed.
Understanding Capacity Versus Resilience
The lessons learned were immediate and profound: having capacity does not equate to resilience. West Africa is served by several significant international networks, including the West Africa Cable System (WACS), African Coast to Europe (ACE), and MainOne cables, all of which provide substantial international capabilities. Yet, their routing patterns and landing configurations mean a single failure can have widespread repercussions. Following the disruptions, internet traffic in affected regions plummeted by more than 50%, leading to increased latency and degraded service quality. Recovery times varied, often stretching into days due to both physical repair challenges and administrative hurdles. For policymakers and investors alike, the message is clear: submarine cables transcend mere communication infrastructure; they are foundational to economic activity.
Economic Implications of Connectivity Outages
Globally, over 95% of internet traffic is transmitted through submarine cables, a crucial statistic highlighted by the International Telecommunication Union. In West Africa, where digitalization is advancing rapidly, the reliability of these systems directly correlates with economic performance. Connectivity outages result in lost trading opportunities, diminished productivity, and weakened investor confidence. Given the current landscape, the Porto Summit underscored the importance of resilience for West African nations, where the digital economy is emerging as a critical growth driver. To sustain this momentum, it is essential to embed resilience into the very fabric of investment decisions rather than addressing it as an afterthought, a notion that is increasingly untenable.
A Long-Term Approach to Digital Infrastructure
There is a growing consensus among global stakeholders, including the World Bank, that digital infrastructure should be approached from a long-term risk and sustainability perspective. Introducing resilience into considerations helps reduce risk premiums, insurance costs, and overall financing decisions. If resilience is not adequately defined, it risks being perceived merely as an added expense. However, when linked to lower downtime and operational continuity, it transforms into a compelling value proposition that can unlock further investment. This understanding is particularly critical in underserved regions.
The Need for Coordinated Policy Frameworks
Addressing the challenges ahead necessitates a shift in perspective. Resilience in submarine cable systems should be regarded as a regional public good, supported by a cohesive policy framework. This is evident in West Africa’s emphasis on regulatory cooperation through WATRA, which unites telecommunications regulators from 16 member countries. The focus on coordination, rather than centralization, ensures that vital aspects of resilience are consistently addressed across various jurisdictions. Essential actions include streamlining landing and clearance procedures, creating robust cable protection frameworks aligned with international standards, implementing pre-established emergency protocols for repairs, and improving data sharing regarding outages and recovery timelines. These steps go beyond technical fixes; they represent regulatory interventions with substantial economic implications.
Incorporating Resilience during Investment Phases
Moreover, it is vital to integrate resilience into the design phase of new investments. This involves prioritizing genuine route diversity, avoiding correlated risks, and aligning regulatory approvals with resilience objectives. The West African case may not be unique; similar vulnerabilities are observable across emerging markets and smaller countries. What is changing is the acknowledgment that resilience is fundamental to the economics of connectivity. For West Africa, the stakes are especially high. The region’s digital economy is expanding swiftly, driven by fintech, mobile broadband, and digital entrepreneurship, all of which depend on robust infrastructure that often goes unnoticed until it falters.
Building a Stronger Future for Digital Growth
Repairing submarine cables in this area comes with significant costs, typically between $1.5 to $2 million for each repair, with many operations dispatched from far-off locations, such as Cape Town. In more complex scenarios—particularly those involving multiple affected cables—costs can soar to $8 million. This situation is further aggravated by the limited availability of specialized repair vessels in Africa, leading to longer repair durations compared to international benchmarks. The disruptions experienced in 2024 served as a critical stress test, exposing vulnerabilities but also creating momentum for reform. Should resilience be woven into policies, designs, and financing frameworks, West Africa can establish a more robust foundation for its digital economy.
When we discuss resilience, it is essential to recognize that it extends beyond infrastructure; it is intrinsically tied to livelihoods. For instance, a young entrepreneur in Lagos running a furniture business on Instagram continues to fulfill orders uninterrupted, while small grocery vendors in Surulere depend on digital payments to keep transactions flowing, even amid strained networks. On a broader scale, banks processing millions of transactions daily, logistics companies coordinating cross-border supply chains, and telecommunications operators delivering data services all rely on uninterrupted connectivity. In such contexts, resilience is not merely an operational standard; it is integral to sustaining economic continuity across both informal and formal segments of the economy.
