Lerkil, Sweden

How the Internet Reaches Lerkil

Lerkil is a small coastal locality in Kungsbacka Municipality, Halland County, on the western coast of Sweden. Its position along the Swedish coastline places it directly on the Kattegat strait, the body of water separating Sweden from Denmark — and it is through this strait that Lerkil's submarine cable connection runs. International internet traffic reaches Lerkil via a direct undersea cable crossing to Denmark, making this compact community a genuine submarine cable terminus rather than simply a transit node.

The Kattegat Cable, currently in draft status, is the single submarine cable landing at Lerkil. It runs beneath the Kattegat to Saeby in Denmark, establishing a direct cross-strait link between the two countries. All international traffic flowing into and out of Lerkil passes through this one connection.

The Cable Serving Lerkil

The Kattegat Cable connects Lerkil, Sweden to Saeby, Denmark, crossing the Kattegat strait. This relatively short route is characteristic of Sweden's submarine cable network, where the average cable length is 335 km. The cable links Sweden and Denmark, meaning that internet packets from Lerkil travel first to the Danish coast before onward routing into the broader European and global internet infrastructure.

Regional Context

Sweden hosts 17 submarine cables across 20 landing points, with the first cable entering service in 1994. Lerkil is one of the smaller single-cable terminuses in this national network. Among its regional peers, Farosund serves three cables, while Klagshamn, Stavsnas, and Stockholm each host two. Klagshamn, also on Sweden's western coast, is a nearby landing point by comparison. Lerkil and Borbby Strandbad share the distinction of being Sweden's only single-cable landing points listed among the country's regional peers, underlining that Lerkil represents a more limited point of entry into the submarine network rather than a major cable hub.

What This Means for Connectivity

Because Lerkil is served by a single submarine cable, all international traffic from this locality flows through the Kattegat Cable alone. An outage on this cable would sever the direct undersea route between Lerkil and Denmark until the link was restored. The destinations reachable via this cable are defined by its landing points: Sweden and Denmark, providing a regional, cross-strait connection rather than intercontinental reach.

For users in Lerkil, onward connectivity beyond Denmark depends on Denmark's own wider network infrastructure. This single-cable arrangement illustrates how even within a well-connected country like Sweden — with 17 cables and 20 landing points nationally — individual localities can rely on a solitary undersea link, making the topology of that one connection directly relevant to understanding local internet resilience.
