Hawaiian Islands Fiber Link (HIFL)

Hawaiian Islands Fiber Link (HIFL) is a domestic submarine cable network within United States, connecting 6 coastal and island locations including Barber’s Point, Hilo, Kahului, Kaunakakai, Lihue, and 1 more. The system provides essential telecommunications infrastructure for communities that would otherwise depend entirely on satellite or microwave links. Within the United States, submarine cables connect Alaska, Hawaii, and coastal regions where terrestrial fiber routes are impractical or prohibitively expensive. This cable is part of GeoCables' continuous monitoring program — RIPE Atlas probes measure latency around the clock, flagging anomalies when RTT deviates significantly from established baselines.
