Azores Fiber Optic System (AFOS)

Azores Fiber Optic System (AFOS) is a domestic submarine cable system within Portugal, linking 7 landing points including Angra do Heroismo, Portugal, Faial, Portugal, Graciosa, Portugal, Ponta Delgada, Portugal and others. It strengthens domestic network resilience in Portugal by providing submarine connectivity between coastal and island communities. GeoCables tracks this cable's health using RIPE Atlas probe measurements, comparing real-time RTT data against baselines to detect performance changes.
