I've done some searching and haven't been able to find much in the last
3 years as to their reliability and suitability as an upstream provider.
Really?  That surprises me; people complain about Cogent on here, roughly,
weekly.  :-)
Sorry, been on this list for quite some time, and I even went back to the archives. I don't see much there that is specific to Cogent doing a bad job. If I go back a few years, I find stuff about Cogent-Telia, Cogent-GBX, and even Cogent-HE IPv6 peering.
For a regional ISP looking for GigE ports in the Chicago/St. Louis area,
is Cogent a reasonable solution? Our gut feeling is that they don't
stack up against a Level3 or Sprint, but they are being very aggressive
with pricing to try and get our business.
The implication of everyone's "in a BGP mix" responses, in case you don't
get it (and I suspect you might not) is that you don't want Cogent to be
your *only* upstream provider.

If you're going to resell the bandwidth as an ISP, best practice says you
should have at least 2 upstreams.  3 or more is better,
This would be a 3rd or possibly a 4th upstream.
Cogent has had a bad habit the last 5 or 10 years of getting into pissing
matches with other carriers about peering, and just cutting them off
(or being cut off)... which of course means that if they're your only
connection to the Internet, then your customers simply can't reach sites
connected to those providers.

So, in short: no matter how agressive they are, they're not the carrier
to have when you're having only one.
