Nordic data center provider atNorth is building a hyperscale facility in Finland. The FIN04 site in Myllykoski (part of the City of Kouvola), 140km northeast of Helsinki, has an immediate power supply available and could expand to "several hundred megawatts" when fully built.

  • This is atNorth's fourth data center in Finland on a 21-hectare plot and will be operational in the first half of 2026.
  • The site will be the tenth data center for atNorth, which spun off from Nordic services company Advania in 2017 and has been acquiring and building data centers backed by Swiss investor Partners Group, which bought atNorth in 2021.
