Nigeria to Cameroon: 502ms and Six Countries to Reach a Neighbor — When a Direct Cable Goes Unused

The Traceroute That Shouldn't Exist

On March 22, 2026, our measurement server in Lagos, Nigeria ran a routine traceroute to Cameroon — Nigeria's immediate neighbor to the east. The two countries share a 1,690 km land border. Cameroon's largest port city, Douala, is closer to Lagos than many Nigerian cities.

Here's what the traceroute showed:

Lagos, Nigeria → Cape Town, South Africa → London, UK → Paris, France → Ashburn, USA → West Seneca, USA → Fortaleza, Brazil

Six countries. Three continents. 502 milliseconds. To reach a neighbor.

The packet left Lagos and immediately headed 9,000 km south to Cape Town via Liquid Telecommunications' African backbone. From Cape Town, it traveled 9,500 km north to London via submarine cable. In London, it was handed to Level 3 (Lumen), then to TELXIUS Cable in Paris. From Paris, the packet crossed the Atlantic to Ashburn, Virginia — 6,000 km west. It then continued to West Seneca, New York, before making a final 7,000 km jump south to Fortaleza, Brazil.

Total distance traveled: approximately 40,000 km. Direct distance Lagos to Douala: 850 km.

That's a ratio of 47:1.

The Cable That Should Have Been Used

Here's what makes this absurd: a direct submarine cable between Nigeria and Cameroon already exists.

The Nigeria Cameroon Submarine Cable System (NCSCS) was launched in January 2016. It's a 1,100 km, 6-fiber-pair system connecting Kribi, Cameroon to Lagos, Nigeria. Design capacity: 12.8 Tbps. It was built by Huawei Marine Networks, funded by the Cameroonian government, and operated by CAMTEL (Cameroon Telecommunications) in partnership with MainOne.

A June 2025 audit by Cameroon's Supreme Court found that CAMTEL uses 92% of NCSCS capacity — the highest utilization of any of their four submarine cables. For comparison, CAMTEL uses only 6% of the SAIL cable, 29% of SAT-3, and 57% of WACS.

So the cable is there. It's being used. But our traceroute from Lagos to a Cameroonian destination didn't touch it.

Why? Peering, Politics, and the Economics of Routing

The answer lies in how internet routing actually works — and it has everything to do with money, history, and geopolitics.

1. Peering agreements don't follow geography. Our Lagos probe connects through the Internet Exchange Point of Nigeria (IXPN) to Liquid Telecommunications. Liquid's backbone runs along Africa's coast to Cape Town and then to London — that's where Liquid has its major peering points. Liquid doesn't have a direct peering agreement with Cameroonian networks, so traffic heading to Cameroon first exits Africa entirely, reaches European/American exchanges where Liquid does peer with carriers that serve Cameroon, and then comes back.

2. Nigeria and Cameroon's complicated relationship. These aren't just any neighbors. The Bakassi Peninsula dispute — a conflict over an oil-rich territory in the Gulf of Guinea — nearly led to war in the 1990s. In 2002, the International Court of Justice (ICJ) ruled in Cameroon's favor. In 2006, Nigeria formally transferred the territory under the Greentree Agreement. But tensions haven't fully disappeared.

The disputed region had oil reserves, rich fishing grounds, and strategic maritime access. Today, separatist movements (including Biafra-related activism in southeastern Nigeria and the Ambazonia conflict in Cameroon's Anglophone regions) continue to create political friction. The border area remains sensitive.

3. Water as a weapon. An often-overlooked dimension: Cameroon controls the Lagdo Dam on the Benue River. When Cameroon releases water — sometimes with little warning — it causes devastating floods in Nigeria's Benue and Kogi states. Nigeria's infrastructure in these regions is weaker, and the floods have displaced hundreds of thousands of people. This creates an asymmetric dependency that colors all aspects of bilateral relations, including telecommunications.

4. Cameroon's digital paradox. Cameroon sits on enormous cable capacity — NCSCS, WACS, SAT-3, SAIL — but uses only 16% of it overall. Internet penetration remains around 5% for fixed broadband. The infrastructure exists but the domestic network to distribute bandwidth inland is underdeveloped. Meanwhile, 83% of African internet traffic is routed through Europe, reducing the value of intra-African cables.

The Bigger Picture: Africa's Routing Problem

The Nigeria-Cameroon detour isn't unique. It's a symptom of a continent-wide problem. Most African internet traffic exits Africa before reaching its destination — even when source and destination are in neighboring countries.

This happens because:

• Internet exchanges are in Europe. Major African ISPs peer in London, Amsterdam, and Marseille, not in Lagos or Nairobi. When two African networks need to exchange traffic, they often do it in Europe.
• Submarine cables follow colonial trade routes. Africa's cables predominantly run north to Europe. Intra-African submarine cables are rare — NCSCS being a notable exception.
• The economics favor transit over peering. It's often cheaper for an African ISP to buy transit from a European carrier than to establish direct peering with a neighboring country's network.

The 2Africa cable (45,000 km, 33 countries) is designed to change this — it's the first system to connect East and West Africa in a continuous loop. But changing routing patterns takes more than laying cables. It requires peering agreements, traffic exchange infrastructure, and political will.

What GeoCables Monitors

Our monitoring data tells the story in numbers:

The direct cable should deliver roughly 15-20ms Lagos-to-Cameroon latency. Instead, the actual route adds 480ms of unnecessary detour. That's 25x slower than it needs to be.

For Nigerian and Cameroonian businesses trying to trade digitally, for voice and video calls between the two countries, for any application that depends on low latency — this routing is a tax. An invisible, unnecessary tax imposed by the architecture of a network that was built to serve Europe, not Africa.

The Hope

Things are changing, slowly. The Africa IXP Association is pushing for more local internet exchanges. The 2Africa cable will provide massive new intra-African capacity. Nigeria recently signed submarine cable deals with Equatorial Guinea. And the NCSCS cable proves that direct connections between neighboring countries are technically and commercially viable.

But until peering agreements follow geography instead of colonial history, packets from Lagos will keep visiting London on their way to Douala.
