Mossbank, United Kingdom

Mossbank: Submarine Cable Landing Point

Mossbank is a landing point located in the United Kingdom, serving as the terminus for a domestic submarine cable connection. As a coastal landing point, it contributes to the submarine cable infrastructure of the United Kingdom, a country that hosts 42 submarine cables across 105 landing points. Mossbank itself hosts one submarine cable, the R100 North, which connects points within the United Kingdom.

The R100 North cable represents an intra-national link, meaning the corridor it enables is a domestic one rather than an intercontinental or cross-border route. This positions Mossbank as a landing point oriented toward serving connectivity within the United Kingdom rather than bridging it to international networks.

Cables Landing at Mossbank

R100 North is the sole submarine cable landing at Mossbank. Measuring 224 kilometres in length, the cable reached ready-for-service status in 2023, making it among the more recently commissioned cable systems in the United Kingdom. Its other endpoints are also located within the United Kingdom, confirming that R100 North is an entirely domestic submarine cable system. The cable's relatively short length is consistent with an intra-national route connecting communities along the British coastline or to offshore island territories within UK jurisdiction.

Regional Context

Within the United Kingdom's submarine cable landscape, Mossbank ranks in the top 91 percent of the country's 105 landing points by cable count, hosting one cable. Compared to more active landing points in the United Kingdom — such as Bude with seven cables, or Blackpool, Southport, and Holyhead with two to three cables each — Mossbank is among the more lightly served landing points in the national network. Its role is narrower in scope than these multi-cable hubs, reflecting its function as a terminus for a single domestic system.

Network Role

Mossbank functions as a single-cable terminus, providing a landing point exclusively for the R100 North system. The corridor this enables is domestic, linking locations within the United Kingdom via a 224-kilometre submarine route that entered service in 2023. As a recently activated landing point, Mossbank contributes to the ongoing expansion and modernisation of the United Kingdom's intra-national submarine cable network.

In the broader submarine cable graph of the United Kingdom — a country with 42 cables and 105 landing points — Mossbank represents one node in a distributed national infrastructure, demonstrating that submarine cables serve not only international connectivity but also domestic routing needs within the UK's geographically dispersed coastal and island communities.
