Scotland-Northern Ireland 4

Scotland-Northern Ireland 4 is a submarine cable system operating within United Kingdom, with landing points at Girvan, Larne. 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 tracks this cable using RIPE Atlas measurements from four probes in Minsk, Almaty, Tbilisi, and Jerusalem, comparing live RTT against historical baselines to catch performance shifts early.
