Laig, United Kingdom

How the Internet Reaches Laig

Laig is a small settlement on the Isle of Eigg, a remote Scottish island off the west coast of the United Kingdom. Its geographic isolation means that connecting it to the wider internet requires dedicated submarine cable infrastructure rather than straightforward overland routes. International and domestic internet traffic reaches Laig through a single submarine cable that links the island to other landing points across Scotland and the Northern Isles.

The R100 North cable is the sole submarine connection serving Laig, and it functions as a terminus point on that cable rather than a transit node. All external internet traffic arriving at or departing from Laig travels along this one route, connecting the settlement to a chain of other landing points within the United Kingdom.

The Cable Serving Laig

The R100 North cable spans 224 km and entered service in 2023, making it a recent addition to the United Kingdom's submarine cable network. It is an entirely domestic cable, connecting Laig to six other UK landing points: Baile Mòr (Isle of Colonsay), Bay of London, Belmont (Shetland), Burravoe (Shetland), Crockness (Orkney), and Belmont. The route spans remote Scottish island communities and the Northern Isles, providing connectivity along a corridor that links some of the most geographically dispersed parts of the UK. This cable carries inter-island and domestic traffic rather than intercontinental traffic, meaning onward connections to international networks occur at other points in the United Kingdom's broader cable infrastructure.

Regional Context

The United Kingdom hosts 42 submarine cables across 105 landing points, with the average cable length running to 1,451 km and the country's submarine cable history stretching back to 1990. Within that large national footprint, Laig represents one of the more remote and lightly served terminuses — connected by a single, short domestic cable rather than by one of the major international corridors landing at sites like Bude (7 cables) or Blackpool (3 cables). Peer landing points such as Holyhead and Lowestoft each host two cables, still putting Laig below the national norm in terms of cable count.

What This Means for Connectivity

Because Laig is served by only the R100 North cable, all of its external internet traffic flows through that single connection. An outage on the cable would sever the settlement's submarine link entirely, leaving no alternative submarine path. The destinations reachable via R100 North are exclusively other UK landing points — Baile Mòr, Bay of London, Belmont, Burravoe, and Crockness — meaning the cable serves a domestic, inter-island purpose, and onward routing to the wider global internet relies on infrastructure at those connected points.

Laig's position as a single-cable, domestic-only terminus illustrates a distinct tier within the United Kingdom's submarine cable network: the outer island communities served by purpose-built short-haul cables designed to close connectivity gaps rather than to carry intercontinental traffic. Understanding this distinction helps clarify how internet access in remote island communities differs structurally from that in the UK's major coastal hubs.
