Eswatini

A landlocked kingdom on the terrestrial grid

Eswatini occupies a small, landlocked area surrounded by South Africa on three sides and Mozambique to the east. That geography is the defining fact of its connectivity: with no coastline, the country has no submarine cable landing stations of its own and cannot connect directly to the subsea infrastructure that carries the bulk of the world's international data traffic.

Instead, Eswatini reaches the global network by routing traffic overland through its neighbours. South Africa is the dominant transit hub in this part of the continent and hosts landing points for numerous major cable systems serving sub-Saharan Africa, the Indian Ocean, and routes northward toward Europe and Asia. Eswatini's international capacity is therefore dependent on cross-border terrestrial links that feed into that broader South African infrastructure, or alternatively through Mozambique, which has its own coastal access to regional cable systems.

What terrestrial dependency means for capacity and resilience

Reliance on terrestrial transit rather than direct cable access carries structural implications. Capacity and pricing are shaped not just by what cables exist offshore, but by the terms on which Eswatini's operators can access the transit networks of neighbouring states. Each additional hop — from a domestic network across a border and onward to a coastal landing station — introduces a potential point of congestion, failure, or commercial friction.

Resilience is similarly constrained. A country with direct landings on multiple independent cable systems can route around a cut or outage on any single system. For Eswatini, a disruption to a key terrestrial corridor or to the South African landing infrastructure that feeds its transit could have outsized effects on international connectivity, depending on what redundant paths are available at any given time.

Satellite capacity provides an additional layer where terrestrial links fall short, and low-earth-orbit satellite services have expanded the options available to landlocked markets across the continent. However, satellite links generally carry higher latency and cost per bit than fibre, making them a supplement rather than a substitute for robust terrestrial transit.

Register status

No submarine cable landings are documented for Eswatini in the Coral Sea Cables register. Because the country is landlocked, none are expected; the connectivity picture is shaped entirely by terrestrial and satellite infrastructure. This profile will be updated as further detail on transit arrangements and terrestrial infrastructure is compiled.
