Sirius North

Sirius North is a submarine cable system operating within United Kingdom, with landing points at Carrickfergus, Saltcoats. It provides dedicated submarine fiber capacity between these locations, supporting telecommunications, internet access, and enterprise connectivity. The United Kingdom, as an island nation and a major global internet hub, hosts one of the densest concentrations of submarine cable landings in the world. GeoCables maintains health checks on this cable using distributed RIPE Atlas probes, with automated anomaly detection triggered when RTT exceeds 4x the historical baseline.
