The New Subsea Cable Race: Who Is Connecting Africa’s Coasts in 2026

Africa’s internet has always depended on a thin, vulnerable thread: the handful of fibre-optic cables lying on the seabed that carry almost all of the continent’s international data traffic. In 2026, that thread is multiplying. From Lagos to Conakry, from Malabo to Marseille, a new generation of subsea cable systems is reshaping how Africa connects to the rest of the world, and who controls the pipes that make that connection possible.

The urgency behind this buildout is not abstract. In March 2024, simultaneous damage to the WACS, SAT-3 and ACE cables off West Africa knocked out internet access across Nigeria, Ghana, and several neighbouring countries for days, disrupting banks, mobile networks, and everyday digital life. A separate round of outages later hit cables serving South Africa and Kenya. Those events turned subsea redundancy from a technical talking point into a policy priority, and the current wave of cable projects is, in large part, a response to that wake-up call.

2Africa’s Long Arrival

The most consequential project of the past few years is 2Africa, the Meta-led consortium cable that, at roughly 45,000 kilometres, is the longest subsea system ever built. Meta confirmed late last year that the core build had been completed, with the network now linking 33 countries across Africa, Europe and Asia and offering a design capacity of up to 180 terabits per second on its main trunks, more than every cable currently serving the continent combined. In Nigeria, 2Africa has landed at two separate points, in Lagos through Bayobab (formerly MTN GlobalConnect) and in Akwa Ibom State through MainOne, giving the country a geographically diversified entry point rather than a single chokepoint at Lagos.

That diversification matters more than the headline capacity figure. Meta’s network engineering leadership has described deploying advanced spatial division multiplexing technology supporting up to 16 fibre pairs per cable, double the capacity of older systems, alongside undersea optical wavelength switching for more flexible bandwidth management. The system’s onward extension into the Middle East and Asia, known as 2Africa Pearls, has been delayed by Houthi attacks on shipping in the Red Sea corridor, a reminder that even the best-engineered cable is hostage to geography it cannot avoid.

Medusa Spreads Along the Atlantic and Mediterranean

While 2Africa dominates headlines, the Medusa Africa system, an 8,700-kilometre network owned by Spanish infrastructure firm AFR-IX Telecom, has quietly become one of the busiest projects on the continent. Its first active segment, ViaTunisia, connects directly into Orange’s infrastructure in Marseille and was co-financed by the European Union’s Connecting Europe Facility Digital programme. Medusa was built as an open-access system, meaning any telecom operator in the region can purchase capacity without depending on a single gatekeeper, a structural choice that newer African cable projects are increasingly adopting.

The cable’s footprint is growing fastest where countries see it as insurance against single points of failure. Guinea recently signed a 25-year construction and maintenance agreement that gives the country, through local operator GUILAB, its second international subsea link via Medusa, with the prime minister describing the project as a matter of sovereignty and national security rather than simply faster broadband. Equatorial Guinea is weighing a similar move, with a feasibility study estimating the cost of joining Medusa at between €20 million and €60 million, with a possible service date of 2029 or 2030.

Nigeria’s Widening Options

Nigeria already hosts more subsea cable landings than almost any other African country, including WACS, SAT-3/WASC, MainOne, Glo-1, Equiano, 2Africa and ACE, plus a dedicated link to Cameroon. That density has not stopped Abuja from pushing for more diversity. In February 2026, Nigeria signed a subsea fibre-optic agreement with Equatorial Guinea to expand regional cybersecurity cooperation and reduce shared exposure to outages. More significantly, the National Information Technology Development Agency has confirmed talks with Google over a dedicated new cable, one explicitly framed around route diversity rather than raw capacity. Officials want a corridor distinct from the Atlantic pathways that all of Nigeria’s existing cables share, so that a single regional incident cannot take down the bulk of the country’s international bandwidth at once.

That subsea ambition is paired with a domestic infrastructure push: a roughly $2 billion, 90,000-kilometre terrestrial fibre project backed by the African Development Bank, intended to fix the inland bottleneck that has historically undercut the benefit of new coastal cables. A cable landing on Nigeria’s shore counts for little if vandalism, road construction, or right-of-way disputes strand that capacity before it reaches a city.

Google, Orange, and the New Entrants

Google has been the most aggressive hyperscaler in the space, building on its Equiano cable with plans for four new infrastructure hubs across northern, western, southern, and eastern Africa, combining landing stations with data centres in cities still to be confirmed. Meanwhile, Orange and a consortium of partners announced in May 2026 the Via Africa cable, a new Europe-Africa route via the Canary Islands, Senegal, Côte d’Ivoire, and Nigeria, explicitly designed to offer a path distinct from 2Africa, Equiano, and Medusa.

What This Means Beyond the Cables

The shift underway is less about any single cable and more about who owns the infrastructure layer underneath Africa’s digital economy. Ownership is moving from traditional telecom consortia toward hyperscale technology firms and open-access infrastructure operators, a change with real consequences for wholesale bandwidth pricing and how much of the value created by new capacity actually reaches local ISPs and end users rather than being captured further up the value chain.

For Nigeria and its peers, the more durable question is not which company lands the next cable, but whether the terrestrial networks, regulatory frameworks, and landing-station competition exist to turn that capacity into cheaper, more reliable internet for the people the cables are meant to serve.
