Quoyness is a submarine cable landing point located in the United Kingdom, situated on the island of Sanday in Orkney, Scotland. As an island community in the northern reaches of the British Isles, its connection to submarine cable infrastructure provides an important link within the United Kingdom's domestic network. One submarine cable currently lands at Quoyness, the R100 North, which forms part of an intra-national corridor connecting different parts of the United Kingdom.
The R100 North cable, with a length of 224 kilometres and a ready-for-service date of 2023, connects Quoyness to other points within the United Kingdom. As both endpoints of this cable lie within the same country, the landing point at Quoyness serves a domestic rather than intercontinental function, enabling connectivity between Orkney and the broader United Kingdom landmass.
R100 North is a 224-kilometre submarine cable with a ready-for-service year of 2023, currently at draft status. Both of its endpoints are located within the United Kingdom, making it a domestic cable that connects Quoyness, Sanday, Orkney, to other parts of the country. At 224 kilometres in length, it is considerably shorter than the United Kingdom average cable length of 1,615 kilometres, reflecting its role as a regional link rather than a long-haul international connection.
Within the United Kingdom's submarine cable network, which spans 66 cables across 125 landing points, Quoyness hosts a single cable and ranks within the top 88 percent of landing points by cable count. Major United Kingdom landing points such as Bude (8 cables), Lowestoft (6 cables), and Blackpool (4 cables) host significantly more cables, reflecting their positions on high-traffic international and domestic routes. Quoyness serves a more focused role as a single-cable terminus serving the island community of Sanday in Orkney.
Quoyness functions as a single-cable terminus within the United Kingdom's domestic submarine cable infrastructure. The R100 North cable it hosts is an entirely intra-national link, connecting Orkney island communities to the wider United Kingdom network. This positions Quoyness as a point of domestic island connectivity rather than a node on international or intercontinental routes.
In the broader United Kingdom submarine cable graph, landing points such as Quoyness represent the network's reach into geographically remote island communities, extending domestic digital connectivity to areas where terrestrial infrastructure is constrained by sea crossings.
