    Now I get why most of you guys say Cogent is a mess!

    Got a server in Buffalo, NY with CC. I'm located around 40 miles from Boston. Got ~110ms of latency.

    Now take a look on the traceroute:

    Well, nothing new. It's been like this since a looong long time. I usually avoid hosting providers using cogent as their main carrier.

    Are you sure that's Cogent's problem?

    I am under the impression it is because CC uses multipath instead of BGP for their datacenter.

    Show the return route, that could also be a congestion issue with Comcast.

    I contacted them (Server Mania, which hosts with ColoCrossing) and they said that "Cogent will be removed from our network within 30-60 days so this will drastically change your routes", so I hope for the best.

    I was counting on that 40ms of latency, 110ms simply killed my project

    That's mainly why we don't have Cogent in the network mix
    I hear it's a common issue with them.

    Could you stop this please?

    1. You do not have a BGP mix, your single homed. There is no BGP 'mix'
    2. Your own website claims or claimed to have Cogent amongst others in your 'BGP mix' a mix that does not exist and never existed.
    http://web.archive.org/web/201308051...d.com/network/

    All these connections are not really true, your not multihomed at all.
    You claim:
    "Global Layer offers a high quality network with a global coverage. For transit they use only the best. Level3, Telia, NTT, Cogent and many more."
    This is a direct claim your company makes (as you own Global Layer).

    Can't they filter out your IP ranges so at least you don't have this trouble anymore? Or are you renting only 1 server, then it's off course a different story.

    Good to see they are improving the network and dropping Cogent out of it

    They won't do that as I got only one server to test their network and service. I'll probably move my project to Choopa in NJ and wait at least one more month before I drop this server.

    Yeah you can do that. Unless they can filter it out for you, but that's something you have to discuss with them

    They could still do something, as you wouldn't be the only one traversing that route.
    I also still think it has something to do with Comcast and not Cogent directly.

    Cogent is typically just fine -- but as has been said many millions of times on WHT, no single carrier is good enough for every location -- which is why you need multiple to route around issues.

    Cogent has capacity issues with VZ and Comcast. In all fairness, several other popular Tier1/Tier2's do as well. As I always state it's FAR more important to have a diverse network with intelligent routing than simple 'have' or 'not have' provider X in the mix.

    +1 this is the key, a well balanced, well mixed network with engineers or devices that can reroute traffic if there are problems. Comcast is a well known bottleneck for various carriers, you might see the same issues now or down the road if you move to another provider.

    Capacity issues with Comcast are much less of a concern if they're being paid for peering. That's why you're better off sending traffic to them via a Tier 2, that has to fork over some bucks, rather than a Tier 1 with a settlement free agreement. Getting a direct connection to them however isn't a good option either, as their own backbone is terrible, so you need to hand off traffic to them as close to the end destination as possible.

    That is a recurring theme on WHT.com.

    We are a happy Cogent customer, with Level3 and Global Crossing in the mix and 7 large peering exchanges. Cogent offers quality routes to ... Cogent customers. We mainly see traffic flowing over our 40 Gbit Cogent lines to other Cogent clients. This works very well for us as some ISPs and some SPs are very heavy on Cogent in their mix and do not peer in the US or Europe.

    Also: the Cogent NOC guys are excellent, very responsive, and when you contact their NOC you actually get a decent response, by technically skilled people.

    and a ton of networks around the world now utilize Cogent -- so theres no way to ignore or not have Cogent in your MIX. They are an asset, period.

    You're calling a different Cogent NOC than I was when I was a customer. These guys didn't even understand RADB, IRR, prefix-lists, etc.

    He has ignored it in every thread it's been mentioned. It's clear users should stay away from his business if he doesn't want to be honest about it. At least at a minimum address the darn thing when it makes him look bad.

    Nlayer, (a tier2 last time I checked) has ongoing capacity issues with Verizon, and possibly Comcast as well in many markets. Just because it's a tier2 doesn't mean they aren't settlement free to certain networks or that they will not run their transit links hot. Back to what I originally said...
