Whats going on at Cogent

I didn't explicitly refer to outbound routing in my post, but maybe this is a tangent. 


The outbound routing is a major factor in CDNs like Cloudflare that are anycasted and serve from the same node the request is received on. For other CDNs, your outbound routing strategy will have a lesser impact. 


I intentionally didn't get technical with my response because "closer" could mean many things, depending on routing configurations, IX connections, CDN magic sauce, etc.

If he only uses a default route then his outbound routing won’t have anything to do with what destinations are closer, etc

I guess first thing's first... you aren't doing anything to force the traffic that way, are you? 

If you've got IPv6 deployed, chances are that no Google will be coming over that Cogent. :-) 

CAIDA says Cogent is bigger.

Being an eyeball network, what's going to impact that kind of usage the most is where the next up connections to Netflix, Google, Akamai, Cloudflare, etc. are located. If they're closer via HE than Cogent, that's where your traffic will come from. 

Looking at your network specifically, Netflix isn't on either IX that you're on, so that HE traffic very well could be a majority Netflix. 

What do your netflows say?

Is he.net smaller than Cogent? Over the past 24 hours we had 6.7 Gbps peak from our HE link and 336 Mbps peak from our Cogent link. This is inbound traffic. We are eyeballs and our outbound is a small fraction of our inbound.

We have been very happy with HE. It was a no brainer over cogent. They are smaller (so are we). When there are issues they are real fast to fix them, you also get the personal touch which you don't get with others.

I don't really get the Cogent/Google peering issues. I've been hearing this for years... How about fixing it already? Telling customer to get other transit providers to get to a given network is really bad. 

On a side note, HE is still HE but they're trying really hard to be a good netcitizen. They've finally pushed filtering for peers: http://routing.he.net . I wouldn't get transit from them, but in some markets, they're the only affordable IP transit providers.

When I call and mention it I’m told that it’s HE’s fault (despite the lovely cake), but when I also bring Google, then they tell me to get a different provider just for this traffic, or meet them at an IX and send my traffic from there. 



About the staff rotation I’ve seen it too, and I’ve also seen an increase in salespeople calling, for example when an AS is registered etc. in addition to the normal calls..

They call me every few months. the last time they emailed me I said I wasn't interested because of the HE issue. I have yet to get another email.......

Have had the same sales rep for several years now; unfortunately he has no ability to fix their IPv6 peering issue so we’re slowly removing circuits, but otherwise for a handful of 10gig DIA circuits it’s been stable. 






Yep, this. Whenever Cogent calls, this is what i tell them. Black-holing HE and Google ipv6 traffic, which is what they do if i use a default route from them, is dead on arrival. Shows they make bad decisions and dont put the customer first, or even create such an illusion.

Anyone else seen terrible support and high turnover of sales/account people at Cogent the last few months? Is there something going on over there internally? I'm sure some people will say Cogent has always been crap but in the past their account reps and support were pretty good. It seems to have gone downhill the last 12 months really bad.
