Hawaii Island Fibre Network (HIFN)

Hawaii Island Fibre Network (HIFN) is a domestic submarine cable network within United States, connecting 7 coastal and island locations including Kaunakakai, Kawaihae, Kihei, Koko Head, Lihue, and 2 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. GeoCables maintains health checks on this cable using distributed RIPE Atlas probes, with automated anomaly detection triggered when RTT exceeds 4x the historical baseline.
