They're lit in the bulding and have a much faster installation interval. How reliable are they?

We've had them direct for transit in LA for about a year. And a year before
that in Denver.
Never had any issues aside from some missing BGP when New York was under
water. Great for US domestic traffic. Not very good for international
traffic.
Let me correct that.
Not very good for pacific international traffic. Atlantic bound is fine.
We have several 100Mb Cogent DIA lines in various places, NYC, Boston,
Portland OR, and it works fine.
It isn't the highest quality, but it works well enough for any office/small
hosting needs.
We've had them since May 2008. Recently upgraded from 100Mb to 250Mb.
Had minor issues here and there (no outages to speak of).
I've had some IPv6 issues since moving the link to dual-stack a few
months back, but we are not deploying IPv6 to end-users yet, so I'll let
them slide on that.
It's worth pointing out that many IPv6 networks are unavailable from
Cogent; so, effectively, in 2013, you still can't get IPv6
connectivity from Cogent.

Hardly something to hold against them until the rest of us can all get
our own houses in order...
Cogent is great if you treat them as a path. I wouldn't use Cogent in place
of single homing a service provider though due to how they run their
network and the subsequent peering disputes that arise. Don't get me wrong,
I like Cogent, they definitely have a good use case, just be cognizant of
how they run their business model / network.

Which other provider? Please name at least one.
Other providers either offer IPv6, or don't. When those other
providers do, good or bad, you can connect to any other IPv6 network
(well, except maybe for Cogent's AS174).
When Cogent offers IPv6, a lot of IPv6 networks are unreachable. No
other provider comes close.
I mean, even their web-site doesn't work from many IPv6-connected
hosts, because there's no route for their network:
li163-XXX:~# telnet cogentco.com http
Trying 2001:550:1::cc01...

Fremont Linode? I see it is unreachable from my ARP Networks VPS (HE v6 transit) and also from behind my HE tunnel at home.
And, presumably, IPv4 either, depending on whom they're having a peering
war with that particular month.
For a client connection, such is probably safe; I don't think I'd run
servers on it.

HE and Cogen't don't peer, even after the cake.

run its course, and gone into the great meme hereafter...}

I'm in the middle of converting IPV4 to dualstack with Cogent. I was told that they don't have IPV6 in the edge in Tampa yet, so they are VLANing us to a core device to give us v6. So by dualstack, they must mean dualstack only from an OSI Layer 1 approach. Heartburn city.....
Robert, do you have any advice from working with their ipv6 stuff, yet?
