Norway’s submarine cable network provides world-class connectivity
Page date: published 15 March 2023; updated 21 September 2026; 5 min read (as rendered).
The article says new submarine fibre links have improved Norway’s connections to European data hubs, reducing latency and adding route diversity for data centres and cloud services. At the time of the article, it described four cable systems in service, two under construction, and three planned: Celtic Norse (Trondheim–Ireland), Leif Erikson (Norway–Canada, operated by Bulk Infrastructure) and Arctic Connect (Kirkenes–Hokkaido). These project statuses are time-sensitive and the article’s update stamp does not confirm which plans were completed.
The Norwegian Data Centre Industry Association’s Bjørn Rønning explains that route alternatives improve resilience when cables are disrupted by construction, fishing trawlers, anchors or geological movement. The article connects cable expansion with demand from data centres, citing Norway’s hydropower and data-centre investments. It names Tampnet Carrier’s North Sea fibre network, with routes connecting Western Norway to Denmark, the Netherlands and the UK; the page reports that its traffic to and from Norway grew over 90% in 2020.
The article notes that new capacity may not all be used and that cable construction carries demand risk. It argues that resilient connectivity can widen location choices for latency-sensitive data centres and benefit broader sectors. Figures, projects and forecasts are those reported in the 2023 article and need current verification.
