Short answer
FirstNet DIA routes international traffic across seven undersea cable systems and multiple global peering hubs, so traffic is automatically engineered around a failed or congested route. If a cable is cut, traffic reroutes without you needing to act.
In detail
International performance depends on where traffic leaves South Africa and how it is routed. For DIA, FirstNet builds that diversity in:
- Capacity across seven undersea cable systems, including WACS, EASSy, SEACOM and 2Africa
- Peering at global hubs including London, New York, Brazil, Germany, Marseilles and Singapore
- Automatic rerouting over alternate paths when a cable is interrupted or a region is congested
- Dedicated 1:1 contention specified on international as well as local traffic
This is one of the clearest differences from standard business fibre, where international contention is limited to a maximum of 1:4, and only during undersea cable failures.
Local traffic is less exposed to cable faults in the first place. FirstNet peers directly at NAPAfrica, JINX, CINX and DINX, so traffic to South African services, banks and platforms stays in the country rather than travelling offshore and back.
