RE: Cogent 100M DIA in Denver
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?

Re: Cogent 100M DIA in Denver
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.

Re: Cogent 100M DIA in Denver
Let me correct that. Not very good for pacific international traffic. Atlantic bound is fine.

Re: Cogent 100M DIA in Denver
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.

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...

Re: Cogent 100M DIA in Denver
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 w...@typo.org wrote: It's worth pointing out that many IPv6 networks are unavailable from insert provider here.

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.

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.
