And would you expect your peer with 400 Mbit/s total to have 400 > reserved on his AMSIX port for you when you see 300 at LINX and LINX goes > down? what makes this a public peering issue.. i see a couple folks already made the point i wanted to do but just because you have capacity to a peer (on a public interface or a dedicated) PI doesnt mean they arent aggregating at their side and/or have enough capacity to carry the traffic where it needs to go this is also about scale, i would hope you arent peering 400Mb flows across a 1Gb port at an IX, this would imho not be good practice.. if your example were 40Mb then it would be different or perhaps 400mb on a 10Gb port. you might even argue there is more incentive to ensure public ix ports have capacity as congestion will affect multiple peers Steve
