Cogent 100M DIA in Denver
They're lit in the bulding and have a much faster installation interval. How reliable are they? Tri Tran
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. On Mon, Oct 14, 2013 at 1:57 PM, Tri Tran <tritran@cox.net> wrote:

Let me correct that. Not very good for pacific international traffic. Atlantic bound is fine. On Mon, Oct 14, 2013 at 2:00 PM, Bryan Tong <contact@nullivex.com> wrote:

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. On Mon, Oct 14, 2013 at 12:57 PM, Tri Tran <tritran@cox.net> wrote:

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.

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?

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. C.
It's worth pointing out that many IPv6 networks are unavailable from <insert provider here>. Hardly something to hold against them until the rest of us can all get our own houses in order... On Mon, Oct 14, 2013 at 01:41:48PM -0700, Constantine A. Murenin wrote:

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. -Blake On Mon, Oct 14, 2013 at 4:18 PM, Wayne E Bouchard <web@typo.org> wrote:

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... ^C li163-XXX:~# C.

Fremont Linode? I see it is unreachable from my ARP Networks VPS (HE v6 transit) and also from behind my HE tunnel at home. -- staticsafe O< ascii ribbon campaign - stop html mail - www.asciiribbon.org Please don't top post.

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.
