Africa’s digital infrastructure agenda is no longer about cable landings alone, but the resilient corridors, exchanges and inland routes that turn bandwidth into a continental market.
Africa’s submarine cable boom has made the continent more visible on the global connectivity map. Over the past two decades, new cable systems have linked African landing points to Europe, the Middle East, Asia and the Americas, expanding available bandwidth, reducing the cost of international capacity in many markets and strengthening Africa’s connection to the global internet.
According to Xalam Analytics, 25 Africa-focused submarine cables have landed since 2010, adding more than 500 Tbps of potential international capacity.
That progress is real. It has improved global access, supported the growth of digital services and helped bring more African markets into the infrastructure conversation. But it has also created a misleading impression: that once enough cables land on African shores, the continent’s connectivity problem is solved.
Absolutely not.
Submarine cables connect Africa to the world. They do not automatically connect Africa to itself.
That distinction is now central to Africa’s digital future. The next phase of the continent’s infrastructure agenda must shift from international access to continental interconnection: the ability for African cities, enterprises, data centres, public institutions, cloud platforms and digital services to connect to each other affordably, directly and resiliently.
This is one of the most important implications of the International Telecommunication Union’s work on submarine cable resilience. The ITU’s International Advisory Body for Submarine Cable Resilience, particularly its working group on connectivity and geographic diversity, highlights a critical issue: global connectivity remains concentrated along limited routes, landing points and geographic corridors. When too much capacity depends on narrow pathways, disruption can produce wide economic consequences.
For Africa, this concern goes beyond cable faults. It speaks to the deeper architecture of the continent’s digital economy.
Many submarine cable routes are shaped by global traffic flows, commercial landing economics and connections to major international hubs. They are built to move traffic efficiently between African markets and the rest of the world. That is valuable, especially for cloud access, global platforms, international financial systems, content delivery and enterprise applications.
But Africa’s digital economy now needs more than outward connectivity. It needs dense, affordable and resilient connectivity between African markets themselves.
A payment platform in Lagos should not depend on inefficient routing to communicate with a partner or data centre in Accra. A university in Dakar should not face high costs or poor performance to exchange research traffic with a counterpart in Nairobi. A public digital system in one African country should not be structurally dependent on distant offshore routes to communicate with a regional platform. A cloud workload serving African users should not routinely travel outside the continent before returning. Even an email between colleagues in the same city should not have to take a journey through another continent before reaching its destination.
Yet this remains the reality in too many cases.
Africa is better connected outward than it is interconnected internally. International bandwidth may be available at the coast, but domestic and cross-border transport can remain expensive, fragile or limited. Traffic between neighbouring countries may still move through distant hubs. Smaller operators may struggle to reach neutral interconnection points. Enterprises may have limited routing choices. Public institutions may rely on narrow connectivity paths. Inland cities may be poorly served compared with coastal capitals.
This is why cable landings are only the beginning of digital infrastructure development.
The real economic value of international capacity is created when that capacity moves inland, connects to multiple routes, reaches carrier-neutral data centres, supports local Internet exchange, enables cloud adoption and serves businesses, governments and communities across the continent.
Without this, Africa can have more bandwidth and still have weak digital resilience.
The problem is structural. National backbones remain fragmented in many markets. Rights-of-way can be expensive and unpredictable. Fibre routes are often duplicated along commercially attractive corridors while underserved regions remain poorly connected. Cross-border links are sometimes weak, underused or commercially difficult. Open-access infrastructure is limited. Local traffic exchange is still insufficient in many markets. Some countries have few data centre and cloud interconnection options. In several cases, the domestic cost of moving capacity inland can undermine the benefit of cheaper international bandwidth.
This creates a continental paradox: Africa may be connected to global digital systems while its own regional digital market remains thin.
That matters for every major digital infrastructure ambition the continent has.
Data centres need reliable connectivity to attract enterprise and cloud workloads. Cloud providers need evidence of demand, strong routing, local interconnection and regional reach. AI infrastructure needs low-latency access to compute, data and users. Digital public infrastructure needs resilience across national and regional systems. Fintech, media, education, health and e-commerce platforms need dependable domestic and cross-border connectivity. Investors need confidence that capacity can reach customers, not simply land at the coast.
In other words, Africa’s next connectivity frontier is not only more international bandwidth. It is African-directed bandwidth architecture.
That means infrastructure designed around African demand, African routing, African cloud markets and African resilience.
The ITU’s emphasis on geographic diversity is therefore especially relevant. For Africa, geographic diversity should not only mean more subsea routes from Africa to other continents. It should also mean more diversity within the continent: more landing stations, more inland fibre paths, more cross-border routes, more neutral exchange points, more regional data centre hubs and more local traffic exchange.
Route diversity must become a policy and investment priority.
A resilient African digital market would have multiple ways for traffic to move between major cities and regions. It would reduce dependence on single corridors, dominant landing points and avoidable offshore detours. It would support local peering so that African traffic can stay closer to African users. It would connect data centres, cloud platforms, Internet exchange points, mobile networks, ISPs, enterprises and public institutions into a more integrated system. It would make digital services less vulnerable to cable cuts, terrestrial fibre failures, regulatory delays or commercial bottlenecks.
This will not happen through market forces alone. Operators cannot solve the problem in isolation. Governments, regulators, infrastructure companies, data centre operators, cloud providers, regional economic communities, development finance institutions and large enterprise buyers all have roles to play.
Governments can reduce rights-of-way costs, simplify permits and support open-access corridors. Regulators can encourage infrastructure sharing, local peering and fair access to essential facilities. Regional bodies can support cross-border fibre corridors and harmonised rules. Investors can finance redundancy rather than only the highest-return routes. Public institutions can become anchor users for local hosting and regional connectivity. Enterprises can demand better routing, resilience and provider diversity.
Africa also needs better measurement. Counting cable landings is no longer enough. The continent should track the diversity of routes, the cost of domestic transport, the strength of Internet exchange points, the level of local traffic exchange, the availability of cross-border fibre, the resilience of landing stations and the reach of inland data centres.
What gets measured will shape what gets financed.
This is why Africa Hyperscalers frames the issue clearly: Africa’s connectivity challenge has moved beyond the coast. The continent’s next task is to build resilient digital corridors that connect African markets to each other.
The goal is not to reject global connectivity. Africa needs strong links to the rest of the world. But those links must be complemented by infrastructure that allows value to circulate within the continent.
A digital economy cannot be built only on outward routes. It needs internal circulation: data moving between African users, businesses, platforms, data centres, public systems and cloud environments.
The old infrastructure question was whether Africa could get connected to the world.
The new question is whether Africa can connect itself well enough to build a digital economy at continental scale.
Africa’s cable boom has made the continent more visible on the global connectivity map. The next phase must make Africa more connected as a continental market.
That is the difference between access and integration.
Access connects Africa to the world.
Integration connects Africa to itself
