The main problem I see is peering wars and a lack of diversity, we have seen a couple incidents where they have dropped all or part of their connectivity to our market (seattle), during the latter they had major packet-loss which was frankly more annoying than them being down... Issues also tend to be a tad more frequent than other providers but on the whole, really not that bad. We basically use cogent as private peering to reach their customers. Operationally the incredibly annoying part is their helpdesk-style attitude towards prefix-lists, if you have a few prefixes this is no big deal but if you are like us and have 30+ downstream ASNs it can get annoying to repetadily explain to techs who don't get it why you need to have them add more routes, do le 24 matching (to limit the number of times we call) or to increase their max-prefix limit. If they were not so cheap I would cancel them just due to the lack of RADB support but at least they have no uRPF filters so I have taken to just doing batch prefix-list updates with them every few months as my sanity-saving solution.

If you want some redundancy you might also try some other similarly priced providers like WBS Connect, HE, or BtN.

I like the haiku! On a serious note, we are considering getting a connection from Cogent. We currently have connections to at&t, Level 3 and TW Telecom. The low cost and high number of peer AS number's seems appealing to us. Every carrier has its issues, so I don't know what to make of the apparent negativity that I am seeing in these haiku threads. I am looking for some first hand experiences to help me make this decision.
Thanks for any assistance!
