An underwater incident off the West African coast in March 2024 triggered a wave of subsea cable failures, disrupting critical systems such as WACS, ACE, MainOne, and SAT-3. This led to widespread disruptions in Nigeria's digital economy, including banking applications, USSD services, and Point-of-Sale transactions. The disruptions resulted in significant economic losses, estimated at ₦273 billion over four days by NetBlocks. The incident exposed Nigeria's vulnerability to failures in critical infrastructure.
Nigeria's digital economy has made significant progress, but its architecture remains exposed to physical concentration and policy or governance risks. The country's connectivity infrastructure is largely concentrated in Lagos, which serves as the principal hub for international submarine cable infrastructure and digital interconnection. This concentration poses a significant risk, as a major incident in the coastal corridor can have far-reaching consequences. Furthermore, Nigeria's terrestrial fibre networks face persistent disruptions from road construction, civil excavation, vandalism, and other forms of infrastructure damage.
The Nigerian Communications Commission reported 5,934 fibre cuts in the first six months of 2026, equivalent to approximately 33 incidents daily. Fibre is no longer just a telecommunications industry asset; it supports critical infrastructure for banking, electronic payments, commerce, government services, logistics, education, and other businesses. The March 2024 outage raised questions about the resilience of domestic digital pathways, with Lagos Chamber of Commerce and Industry President Gabriel Idahosa calling for greater investment in locally hosted switching and transmission infrastructure.
To address these vulnerabilities, Nigeria needs to develop layers of redundancy that prevent the failure of one route, facility, or provider from becoming a national disruption. This can be achieved through geographically separated data and network infrastructure, alternative terrestrial fibre routes, greater diversity in subsea cable landing points, stronger protection for critical fibre corridors, and deeper domestic interconnection. The Internet Exchange Point of Nigeria (IXPN) provides an important part of this architecture by enabling networks to exchange domestic traffic locally.
Strengthening local peering and interconnection can reduce Nigeria's exposure to external connectivity failures. The objective is not to eliminate every possible point of failure but to ensure that the failure of one component does not automatically become the failure of an entire service. This is the essence of digital resilience. The protection of telecommunications infrastructure has become a national-security issue, with President Bola Tinubu signing the Critical National Information Infrastructure (CNII) Designation Order in June 2024.
The CNII Designation Order formally recognises critical ICT infrastructure as assets whose protection is important to national security and economic activity. However, physical protection is only one side of the resilience equation; the other concerns the legal framework governing state intervention in telecommunications. The Nigerian Communications Commission has emergency powers under Section 148 of the Nigerian Communications Act 2003, which can include suspending a licence or taking temporary control of network facilities.
The practical consequences of emergency telecommunications intervention were demonstrated in September 2021, when telecom services were suspended across Zamfara State due to security concerns. Such interventions may arise from genuine security imperatives, but they also expose a policy tension that deserves greater attention as telecommunications infrastructure becomes increasingly critical to the economy. A network designed for resilience must be capable of maintaining essential services during disruption.
Key points
- Nigeria's digital economy is vulnerable to disruptions due to a single point of failure in its critical infrastructure.
- The country's concentration of connectivity infrastructure in Lagos poses a significant risk to its digital economy.
- Developing layers of redundancy and strengthening local peering and interconnection can improve Nigeria's digital resilience.
