Why Is Nigeria Losing Billions of Naira to Fibre-Cable Cuts Every Year?

Nigeria loses an estimated N27 billion to N35 billion every year to fibre-optic cable cuts through a combination of direct repair costs, lost operator revenue, and wider economic disruption. The figure reflects thousands of incidents that repeatedly sever the terrestrial backbone carrying internet, mobile data, and critical business traffic across the country.

The Scale of the Problem

Fibre cuts account for the majority of major network outages reported to the Nigerian Communications Commission. In the first quarter of 2026 alone, operators logged hundreds of significant service disruptions, with fibre damage responsible for roughly three-quarters of them. Individual operators report thousands of cuts annually; some months have seen hundreds of incidents concentrated in high-traffic corridors. Industry estimates place combined yearly losses in the N27–35 billion range when repairs, compensation, emergency response, and revenue leakage during downtime are added together. Direct repair spending alone often exceeds N14 billion.

These numbers matter because fibre forms the high-capacity links between cities, data centres, base stations, and international submarine cables. When a trunk is cut, the effects cascade: mobile sites lose backhaul, banks and payment platforms slow or fail, hospitals and government services lose connectivity, and ordinary users experience dropped calls or data blackouts.

Primary Causes

The largest single driver is civil works. Road construction, drainage projects, pipeline installation, and general excavation frequently damage buried cables because coordination between contractors, state agencies, and telecom operators remains weak. Many sites lack accurate, shared maps of underground infrastructure. Right-of-way processes are inconsistent across states, and the absence of a reliably enforced “call-before-you-dig” system means excavators often discover fibre only after it has been severed.

Vandalism and theft form the second major category. Cables and associated equipment are targeted for perceived scrap value or, in some cases, to create communications gaps. Access denial by communities or landlords who block technicians from repairing or maintaining sites compounds the problem, turning temporary damage into prolonged outages. In a smaller number of cases, deliberate sabotage has been reported in insecure areas.

These causes interact with structural weaknesses: high right-of-way charges that consume capital that could otherwise fund better protection or deeper burial, limited use of duct sharing, and slow enforcement of existing critical-infrastructure protection rules.

Economic and Social Consequences

Beyond the direct bill paid by operators, fibre cuts impose costs on the wider economy. Businesses lose trading hours, digital payments stall, remote work and online education are interrupted, and emergency services face communication gaps. Capital that could expand coverage into underserved areas is instead diverted to repeated repairs and cable relocation. MTN, for example, has reported budgeting billions of naira annually simply to move vulnerable fibre away from construction corridors—money that could have built hundreds of additional kilometres of new network.

The cumulative effect slows Nigeria’s broadband and digital-economy targets. Operators continue to invest heavily in new fibre and towers, yet the rate of destruction offsets part of that progress and raises the effective cost of every kilometre deployed.

Why the Problem Persists

Several institutional gaps keep the cycle going. Planning for roads and other civil projects often proceeds without mandatory, real-time consultation with telecom infrastructure owners. Penalties for damaging critical cables are either insufficient or poorly enforced. Public awareness that fibre carries data rather than valuable copper remains low in some communities, feeding both accidental and intentional damage. Multiple layers of approval and inconsistent state-level charges further complicate proactive protection and rapid restoration.

Recent regulatory attention, including targets to reduce cut incidents and efforts to improve coordination frameworks, shows recognition of the issue. Lasting improvement will require consistent mapping of underground assets, mandatory pre-excavation checks, stronger sanctions, shared duct infrastructure, and closer alignment between transport, works, and communications authorities.

Nigeria’s annual multi-billion-naira losses to fibre-cable cuts stem mainly from uncoordinated civil works, vandalism, and weak protective systems around a network that underpins almost every modern economic activity. Until excavation practices, enforcement, and infrastructure planning catch up with the volume of fibre already in the ground, the financial and service drain will continue to tax operators and the broader economy alike.

Frequently Asked Questions

How much does Nigeria lose each year to fibre cuts?
Industry estimates put the combined cost of repairs, lost revenue, and operational disruption at between N27 billion and N35 billion annually.

What causes most fibre-optic cable cuts?
Road construction, excavation, and other civil works are the leading cause, followed by vandalism, theft, and access denial by communities or property owners.

How do fibre cuts affect ordinary users?
They produce network outages that disrupt mobile data, voice calls, online banking, business transactions, and public services until repairs are completed.

Why is coordination with construction projects so difficult?
Many projects proceed without reliable shared maps of underground telecom infrastructure or mandatory pre-dig notification systems.

Are there laws protecting telecom cables?
Critical national information infrastructure rules exist, but enforcement and practical coordination on the ground remain inconsistent.

Can the losses be reduced?
Yes, through better mapping, enforced call-before-you-dig procedures, shared ducts, stronger penalties, and closer planning between road agencies and telecom operators.
