This year I've been seeing what appears to be an increasing trend among service providers.. making the decision to leave public peering. I'm sure others on this list as seeing that trend as well. I have a couple of guesses, but I'm curious , and I wanted to get some other thoughts as to the "why". I don't have exact numbers, but off the top of my head, I'd guess somewhere around two dozen of our peers have left various peering exchanges. Quick couple I checked still appear to be operational as a company, so I'm willing to remove "death" as a valid reason. I realized that paid transit is down at almost obscene levels, but is that enough of a reason to increase hop-count, latencies, etc? Why disconnect from public mostly-free peering? -donn
