Carriers on-net
9
Ostre Aker vei 18 in Oslo is a carrier building, and Arelion runs it. Telia Company agreed to sell its international carrier arm to Polhem Infra in October 2020 for SEK 9.45 billion, closed the sale in June 2021, and the business took the Arelion name on 19 January 2022; Telia holds no Oslo facility now. OKR is the site code for the Ostre Aker vei address. Nine networks and two carriers take service there, with no exchange in the building: the profile of a Tier 1 backbone node rather than a peering floor.
