Zayo Festoon

Zayo Festoon is a submarine cable system operating within United States, with landing points at Los Angeles, San Luis Obispo, Santa Barbara. It provides dedicated submarine fiber capacity between these locations, supporting telecommunications, internet access, and enterprise connectivity. 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.
