Malawi

A landlocked position with long consequences

Malawi sits at the southern end of the East African Rift Valley, bordered by Tanzania to the north, Mozambique to the east and south, and Zambia to the west. It has no coastline. That single geographic fact removes submarine cable infrastructure from the domestic equation entirely: no cable can land on soil that touches no sea.

The practical consequence is that all of Malawi's international bandwidth must travel overland before it reaches a coast — and a submarine cable system — anywhere. Terrestrial fibre routes through neighbouring countries carry traffic toward landing points on the Indian Ocean seaboard, principally in Mozambique and Tanzania, where several major East African cable systems come ashore. The path to the global network is therefore indirect by definition, adding transit hops, potential points of failure, and dependency on the infrastructure decisions of other nations.

Satellite as a parallel path

Alongside terrestrial transit, satellite connectivity has historically played a meaningful role for landlocked African states where overland fibre build-out has been slow or patchy. Satellite provides a route to international capacity that bypasses the terrestrial choke points entirely, though typically at higher latency and greater cost per megabit than fibre-based alternatives. The balance between the two reflects both the maturity of regional terrestrial networks and the economics available to operators in-country.

What the register shows

The Coral Sea Cables register currently documents no submarine cable systems with a landing point in Malawi — a finding that reflects geography rather than any gap in the dataset. The register covers submarine infrastructure; Malawi's international connectivity exists at the terrestrial and satellite layer, upstream of the point where cables meet the ocean floor.

Work to document the full chain of transit infrastructure linking landlocked African countries to coastal cable landing stations is ongoing. Where that picture becomes clearer — including the specific terrestrial routes and the coastal systems they feed into — this profile will be updated accordingly.

Implications for capacity and resilience

Without direct cable landings, the standard framework for assessing resilience — counting diverse cable routes, identifying single-cable dependencies, mapping redundant paths — does not apply in the usual way. Resilience for Malawi is instead a question of how many independent terrestrial corridors reach the coast, and how many distinct landing points those corridors serve. That analysis sits at the intersection of submarine and terrestrial infrastructure, and it is a dimension this register continues to develop.
