Hi, We're a small ISP / datacenter with a Time Warner fiber-based DIA contract that is coming up for renewal. We're getting much better pricing offers from Cogent, and are finding out what Level 3 can do for us as well. Both providers will use Time Warner fiber for last mile. My questions are: - Will we be sacrificing quality if we spring for Cogent? (yesterday's Cogent/Verizon thread provided some cold chills for my spine) - Is there a risk with contracting a carrier that utilizes another carrier (such as Time Warner) for the last mile? (i.e. if there is a downtime situation, are we going to be caught in a web of confusion and finger-pointing that delays problem resolution)? - How are peoples' experiences with L3 vs TWC? Although I assume everyone on the list would be interested in what others have to say about these questions, out of respect for the carriers in question, I encourage you to email frank opinions off list. Or if there are third party tools or resources you know that I could consult to deduce the answers to these questions myself, they are most welcome. Thanks, Adam
