atNorth, a Nordic colocation, high-performance computing, and artificial intelligence service provider, has announced an expansion of its partnership with Nordic IT services corporation, Advania. This expansion will provide additional capacity at atNorth's ICE03 site in Iceland, which opened last year. Advania is a long-standing customer of atNorth at its ICE01 site in Reykjavík and other data centers in Sweden and Finland. The expansion to the ICE03 campus will enhance data security, redundancy, and performance optimization. The ICE03 data center is located in Akureyri, in the north of Iceland, benefiting from the country's cool climate and renewable energy sources. This announcement follows atNorth's recent expansion of three new sites in Finland and Denmark.
