Meltingpot Indianoceanic Submarine System (METISS)

Overview

The Meltingpot Indianoceanic Submarine System, known as METISS, is a regional submarine cable system spanning approximately 3,200 kilometres in the western Indian Ocean. It connects four landing points across Madagascar, Mauritius, Réunion, and South Africa, serving the island nations and territories of this corridor alongside the African mainland coast.

Route and Landings

In Madagascar, METISS lands at Fort Dauphin, on the southern coast of the island.

In Mauritius, the cable comes ashore at Baie du Tombeau, located on the northwestern coast of the island.

In Réunion, the landing point is Le Port, on the island's northwestern shore.

In South Africa, the cable lands at Umbogintwini, situated on the KwaZulu-Natal coast south of Durban.

Ownership and Operators

METISS is owned by a consortium of six telecommunications companies: Canal+ Telecom, CEB Fibernet, Emtel, SFR, Telma (Telecom Malagasy), and Zeop (including Reunicable). The ownership reflects the regional character of the system, with operators drawn from each of the territories the cable serves. Telma is Madagascar's national telecommunications provider, while Emtel and CEB Fibernet are Mauritian carriers, and Canal+ Telecom, SFR, and Zeop are active in the French overseas territory of Réunion.

Status and Timeline

METISS entered service in 2021. The system is currently operational, providing connectivity across its four-country route in the western Indian Ocean.

Regional Context

The western Indian Ocean corridor connecting South Africa, Madagascar, Mauritius, and Réunion is served by several submarine cable systems of varying scale. METISS, at 3,200 kilometres, is a compact regional system compared to corridor neighbours such as EASSy (10,500 km, in service since 2010), DARE 1 (4,854 km, also entering service in 2021), and the much longer intercontinental systems including Equiano, ACE, 2Africa, and Project Waterworth that touch South Africa and Madagascar as part of broader routes. METISS is distinguished by its direct focus on the island territories of Mauritius and Réunion alongside Madagascar and South Africa, rather than serving as a long-haul intercontinental link.

Recent performance measurements across 198 ping tests over the last 60 days record an average round-trip latency of 147.2 milliseconds, with a best recorded result of 48.9 milliseconds.

Strategic Role

METISS provides direct submarine cable connectivity between South Africa, Madagascar, Mauritius, and Réunion — four distinct territories in the western Indian Ocean. By landing in all four locations, the system supports telecommunications between island communities and the African mainland coast within a relatively contained geographic footprint. The multi-operator ownership structure, spanning carriers from each served territory, reflects a cooperative model suited to regional connectivity needs in this part of the Indian Ocean.
