South Sudan

Connectivity without a coastline

South Sudan is landlocked, which removes submarine cables from the picture entirely. With no coast and no landing points, the country cannot connect directly to the global undersea network — every bit of international bandwidth must arrive by other means.

In practice, that means one of two paths: satellite links beamed directly to ground stations within the country, or terrestrial fibre circuits transiting through neighbouring states before reaching a coastal landing point elsewhere on the continent. Both routes carry significant limitations. Satellite capacity tends to be expensive and constrained, with latency that undermines real-time applications. Terrestrial transit introduces dependency on the political stability, infrastructure quality and commercial arrangements of multiple third countries — Uganda, Kenya, Ethiopia and Sudan all sit along plausible routing corridors, each carrying its own set of geographic and logistical complications.

What landlocked means for resilience

For countries with diverse submarine cable access, resilience is built through redundancy — multiple cables, multiple landing points, multiple paths to the open ocean. South Sudan has none of these levers available in the conventional sense. Resilience here depends instead on the diversity of overland routes and the availability of satellite backup, a considerably thinner safety net.

The cost implications are also material. Transit bandwidth purchased through neighbouring networks typically carries a premium over capacity obtained at a coastal landing point. That premium flows through to retail pricing, slowing the economics of connectivity expansion.

Geography as the defining constraint

The country's position in the centre of the continent — far from the Indian Ocean coast to the east and even further from West Africa's Atlantic cable corridors — means that any fibre path to a submarine cable landing point covers considerable distance through complex terrain and across multiple borders. The East African cable systems that serve Kenya, Tanzania and the wider region represent the most logical eventual gateways, but reaching them requires overland infrastructure that remains underdeveloped across much of the region.

Register status

The Coral Sea Cables register currently has no submarine cable connections documented for South Sudan. This reflects the country's landlocked geography rather than a gap in research. The register will note any future developments — including terrestrial backbone links with direct bearing on how the country accesses coastal cable systems — as documentation is compiled.
