At the 2026 International Submarine Cable Resilience Summit in Porto, Portugal, a clear message resonated among global stakeholders resilience is no longer just a technical issue; it is a critical economic priority. For West Africa, this reality is both urgent and far-reaching.
With a combined GDP exceeding $800 billion, the region is experiencing rapid digital transformation. Its digital economy spanning fintech, e-commerce, cloud services, and broadband connectivity currently contributes between $100 billion and $150 billion annually, with strong projections for continued growth. Digital platforms are increasingly bridging infrastructure gaps, enhancing productivity, attracting investment, and generating employment.
However, this progress is built on a vulnerable foundation.
The widespread submarine cable disruptions of March 2024 exposed significant weaknesses in the region’s connectivity infrastructure. Multiple countries experienced degraded internet services for hours and, in some cases, days. Financial systems slowed, digital platforms went offline, and businesses dependent on cloud services faced severe operational setbacks.
While submarine cable faults are not uncommon globally often caused by fishing activities, anchoring, or natural seabed movement the scale of the West African disruption was unprecedented. Several major cable systems were affected simultaneously, drastically reducing bandwidth and overwhelming existing redundancy mechanisms.
The takeaway was unmistakable: capacity alone does not guarantee resilience.
West Africa is connected by key international submarine cable systems such as WACS, ACE, and MainOne. Although these systems provide substantial capacity, their routing similarities and landing configurations create shared vulnerabilities. During the 2024 outage, internet traffic in some countries dropped by over 50 percent, while latency surged and service quality declined. Restoration efforts, in certain instances, took several days due to both technical and administrative challenges.
These events underscore a critical reality submarine cables are not merely telecommunications infrastructure; they are the backbone of economic activity. According to the International Telecommunication Union, over 95 percent of global internet traffic is carried through submarine cables. For a region rapidly embracing digital solutions, their reliability is directly tied to economic performance.
At the Porto Summit, the Executive Secretary of the West African Telecommunications Regulators Assembly (WATRA) emphasized that West Africa’s digital momentum cannot be sustained without resilient infrastructure. Historically treated as a secondary concern, resilience must now be embedded at the core of infrastructure planning and investment.
Global institutions, including the World Bank, are increasingly aligning with this perspective. Resilience is now a key factor influencing investment decisions, insurance costs, and risk assessments. When properly integrated, it becomes a value driver that attracts capital rather than a cost burden.
Yet, a fundamental challenge remains. While submarine cable systems operate regionally, governance frameworks are largely national. Differences in permitting processes, emergency response protocols, and cable protection enforcement introduce inefficiencies and risks. During outages, delays in customs clearance, port access, and inter-agency coordination can significantly prolong restoration timelines, ultimately increasing the cost of capital for investors.
Addressing these challenges requires a shift toward regional coordination. Through WATRA’s 16 member states, efforts are underway to harmonize regulatory frameworks while maintaining national sovereignty. Key focus areas include streamlined permitting processes, stronger cable protection measures aligned with global standards, pre-established emergency repair protocols, and improved data sharing on outages.
Equally important is embedding resilience at the design stage of new infrastructure. This involves ensuring route diversity, minimizing correlated risks, and aligning regulatory approvals with resilience objectives.
The financial implications are also significant. Submarine cable repairs in the region typically cost between $1.5 million and $2 million per incident, with complex multi-cable disruptions reaching up to $8 million. Limited availability of specialized repair vessels in Africa further extends restoration timelines, often requiring mobilization from distant locations such as Cape Town.
Beyond infrastructure, resilience has a direct human and economic impact. It enables small business owners, digital entrepreneurs, and large enterprises alike to operate without disruption. From a young entrepreneur running an online business in Lagos to financial institutions processing millions of daily transactions, uninterrupted connectivity is essential.
When systems fail, the consequences are immediate lost revenue, disrupted trade, and diminished confidence. In a region where many operate with limited financial buffers, even short outages can translate into significant economic hardship.
The 2024 disruptions served as a wake-up call. They revealed critical vulnerabilities but also created momentum for reform. By embedding resilience into policy, infrastructure design, and financing frameworks, West Africa can build a stronger, more reliable foundation for its digital economy.
In today’s interconnected world, resilience is not optional it is the cornerstone of sustainable growth.
