There have been a few discussions over the last few months on Cogent - Seems the response is mixed, depending if you're on Cogent or old PSINet facilities. My experience has been that you get what you pay for - They're the cheapest, that's for sure. I've not heard anything about them in the last couple of months, but the last year has been filled with almost monthly service outages or congestion.

Similar experience here, we had them as one of our five upstreams for web hosting traffic for two years. We'd get regular complaints from customers about slow sites and trace it back to their traffic involving the cogent link so we began prepending three times to cogents peers in an attempt to only see traffic to and from cogent customers use that link under normal circumstances, but there were still enough regular issues that we dropped them a few months ago. Their bgp community support encompasses maybe four things you can set too, it's next to nothing. David
