Why don't you read what someone at
Level 3 has to say about the issue?
"Level 3 has 51 peers that are interconnected in 45 cities through over 1,360 10 Gigabit Ethernet ports"
"The average utilization across all those interconnected ports is 36 percent."
"A port that is on average utilised at 90 percent will be saturated, dropping packets, for several hours a day. We have congested ports saturated to those levels with 12 of our 51 peers. Six of those 12 have a single congested port, and we are both (Level 3 and our peer) in the process of making upgrades – this is business as usual and happens occasionally as traffic swings around the Internet as customers change providers."
"the remaining six peers with congestion on almost all of the interconnect ports between us. Congestion that is permanent, has been in place for well over a year and where our peer refuses to augment capacity. They are deliberately harming the service they deliver to their paying customers. They are not allowing us to fulfil the requests their customers make for content."
"
Five of those congested peers are in the United States and one is in Europe."
Five major US ISP's all deliberately refusing to upgrade their interconnect. How many "major" ISP's do you know of in the US?
