Much of Norway's internet traffic runs through Sweden, but traffic to you from my Norwegian isps goes via London or Frankfurt into your network.
My 1. ISP Ventelo, (Norway's second largest ISP), are present on NETNOD.
My 2. isp, use TeliaSonera for international traffic, but I get routed through Germany instead of directly to Sweden.
Please try to improve your peering with them, it would result in better routing to large parts of Norway.

TeliaSonera: http://www.peeringdb.com/view.php?asn=1299
Global Crossing to, since they are the other large international traffic provider in Norway.
