How ₦273bn Digital Shock Exposed Single Point of Failure Threatening Nigeria’s Digital Economy

Nigeria’s growing dependence on digital connectivity is exposing a vulnerability with potentially far-reaching economic consequences, with thousands of fibre disruptions, concentrated network infrastructure and other weaknesses raising concerns about the resilience of the systems supporting the country’s digital economy.

The scale of the potential economic cost was demonstrated in March 2024, when an underwater incident off the West African coast disrupted the WACS, ACE, MainOne and SAT-3 submarine cable systems.

Banking applications and some USSD services became unavailable, Point-of-Sale (POS) transactions were disrupted, while businesses struggled to access digital services.

NetBlocks estimated that the four-day disruption cost Nigeria about ₦273 billion in economic activity, providing a stark measure of how deeply telecommunications infrastructure has become embedded in banking, commerce, logistics and everyday economic activity.

But the lesson from the incident extends beyond submarine cables.

Nigeria’s digital economy is increasingly supported by an infrastructure architecture in which critical networks, routes and facilities remain vulnerable to physical disruption. At the same time, the country faces a policy challenge over how to maintain network availability while retaining the ability to intervene during serious security emergencies.

The result is two broad resilience challenges: physical vulnerability and governance risk.

The physical vulnerability is particularly evident in the country’s terrestrial fibre infrastructure.

In the first six months of 2026 alone, 5,934 fibre cuts were recorded, according to data from the Nigerian Communications Commission (NCC), an average of roughly 33 incidents every day. Road construction, civil excavation, vandalism and other infrastructure damage continue to threaten terrestrial fibre routes.

The significance extends well beyond telecommunications companies.

Fibre networks now support electronic payments, agency banking, POS terminals, digital commerce, government services, logistics, education and an expanding range of businesses. Damage to a critical fibre route can therefore become a disruption to economic activity.

The 2024 subsea outage also highlighted the importance of resilient domestic digital pathways.

Lagos Chamber of Commerce and Industry President, Gabriel Idahosa, subsequently called for greater investment in locally hosted switching and transmission infrastructure, arguing that domestic transactions should, as far as possible, remain within resilient Nigerian networks rather than depend unnecessarily on international connectivity.

That principle is becoming more important as electronic transactions expand. A payment originating in Lagos and destined for another Nigerian city should, where technically feasible, be capable of remaining within domestic networks even when an international connectivity route is disrupted.

Nigeria has already begun developing parts of that architecture.

The Internet Exchange Point of Nigeria (IXPN) enables networks to exchange domestic traffic locally, reducing unnecessary reliance on international transit. Deeper domestic peering and interconnection can therefore help reduce the impact of external connectivity failures.

The same principle applies to physical infrastructure.

Nigeria has begun diversifying its international connectivity, including through submarine systems landing outside Lagos. Yet Lagos remains the country’s principal hub for international submarine cable infrastructure and digital interconnection.

Greater geographic diversity of cable landing points, alternative terrestrial fibre routes, geographically separated data infrastructure and stronger protection of critical fibre corridors would reduce the likelihood that damage in one location could cascade into a much wider national disruption.

The objective is not to eliminate every possible point of failure. That is impossible in a complex digital ecosystem. Rather, Nigeria needs sufficient redundancy to ensure that the failure of one cable, route, facility or network component does not automatically become the failure of critical services.

That is the essence of digital resilience.

It is also why the protection of telecommunications infrastructure has increasingly become a national-security issue.

In June 2024, President Bola Tinubu signed the Critical National Information Infrastructure (CNII) Designation Order, formally recognising critical ICT infrastructure, including telecommunications infrastructure, fibre-optic networks and data centres, as assets whose protection is important to national security and economic activity.

The designation reflects how deeply digital infrastructure is now embedded in national life. When connectivity fails, the consequences are no longer confined to telecom operators and their customers. Banks, businesses, public institutions, hospitals, logistics companies and millions of individual users can be affected.

But protecting infrastructure is only one side of the resilience equation.

The other concerns the legal framework governing state intervention in telecommunications.

Under Section 148 of the Nigerian Communications Act 2003, the Nigerian Communications Commission has emergency powers that can include suspending a licence, taking temporary control of network facilities, or withdrawing wholly or partially the use of services or network facilities in a public emergency or in the interest of public safety.

The practical consequences of emergency telecommunications intervention were demonstrated in September 2021, when telecom services were suspended across Zamfara State amid security concerns.

Such measures may be taken in response to genuine security imperatives. But as telecommunications become increasingly critical to the economy, the economic and social consequences of broad or prolonged disruptions also require consideration.

The Communications Act itself recognises the importance of continuity. Section 149 provides for disaster and emergency planning, including arrangements aimed at the survivability and recovery of services and network facilities during a disaster, crisis or civil emergency.

The policy challenge, therefore, is not simply whether emergency powers should exist. It is how those powers can operate alongside the resilience requirements of an economy that increasingly depends on uninterrupted connectivity.

Where a security threat is geographically specific, the broader policy objective should be to achieve the necessary security outcome while minimising unnecessary disruption to unaffected citizens, businesses and critical services. Clear procedures, proportionality, accountability and appropriate review mechanisms can help reconcile security requirements with continuity of essential digital services.

NCC Executive Vice Chairman, Dr Aminu Maida, has stressed the strategic importance of resilience. Speaking in 2025, he described modern infrastructure as “virtual, interconnected, and crucial to every sector of society,” adding that “resilience is not a luxury—it is a national imperative.”

That imperative is becoming harder to ignore.

Nigeria’s electronic payments ecosystem continues to expand, while businesses increasingly depend on mobile connectivity, cloud services, digital platforms and online transactions. The country’s digital infrastructure is no longer simply an enabler of the economy; in many sectors, it has become part of the economy’s operating system.

The ₦273 billion estimated impact of the 2024 subsea disruption therefore carries a larger lesson.

Nigeria does not simply need more connectivity. It needs connectivity that can withstand disruption.

That requires greater diversity in international and terrestrial routes, stronger protection of critical infrastructure, deeper domestic interconnection, resilient data and power systems, and a regulatory framework that balances legitimate national-security requirements with the continuity of essential digital services.

The country cannot build a resilient digital economy around infrastructure in which several critical connections can fail together.

The lesson of the 2024 outage was not that Nigeria had no redundancy. It was that too many critical parts of its digital infrastructure could still be exposed to correlated failure.

As Nigeria’s digital economy expands, the measure of progress should therefore be more than the number of cables laid, towers deployed or gigabytes consumed.

It should also be measured by how much economic activity can continue when one of those critical connections fails.
