An anonymous reader writes: Level 3, an internet transit provider, claimed in a recent blog post that six ISPs that it regularly does business with have refused to de-congest most of their interconnect ports. 'Congestion that is permanent, has been in place for well over a year and where our peer refuses to augment capacity.' Five of the six ISPs that Level 3 refers to are in the U.S., and one is in Europe. Not surprisingly, 'the companies with the congested peering interconnects also happen to rank dead last in customer satisfaction across all industries in the U.S. Not only dead last, but by a massive statistical margin of almost three standard deviations.' Ars Technica reports that ISPs have also demanded that transit providers like Level 3 pay for access to their networks in the same manner as fringe service providers like Netflix.
