Cogent for ISP bandwidth

Tue May 15 13:00:24 UTC 2012

Let me say it differently.

Take a look at thier AS174  peering relationship, (e.g using  
bgp.he.net), you can see that they (Cogent) are very well connected 
(directly) with all of the major networks. (this is what I meant by, 
they deal with all of the major carriers).

Your experience with traffic is very different from what we have seen, 
while I  can understand that, it can be due to many factors.

Based on AS Peering relationships, it would appear that Major / Most of 
the end user ISP's have them in their mix. I my opinion the Hosting 
providers use Cogent as a way to off load incoming  traffic from the 
more expensive carriers. Cogent performance is very decent if the 
traffic is all on-net ... they typically have issues when traffic is 
crossing their network, i.e. coming in and going out via their peers to 
other networks.

While the Kia and Ferrari example is cute, but when put into the context 
of 'Traffic' or 'Speed limit', then neither has the advantage. One might 
look good driving in a Ferrari.. but I digress.... packets are agnostic 
of what brand of router they are traveling thru or whose network they 
are transiting.

We are in agreement, that Cogent makes a good backup secondary or 
tertiary in a mix of Ip transit. However having said that it is valuable 
to check the bgp peering relationships of the different providers that 
you have, to make sure that you are choosing providers based on actual 
diversity rather than a perceived one.

Aside from that what matters the most is eye ball user connectivity and level3 , AT&T, Verizon significantly have more eye balls connected directly to there network then cogent , we have cogent and level3 and 5 other providers on our Chicago network , with out any traffic engineering almost every thing will come in or go out level3, we use traffic optimizing equipment to automate our commit levels and also do performance based routing adjustments , I literally have to put a gun to its head to get a descent amount of traffic out to cogent , you may say it's a matter of opinion but statistics don't lie, even Telia out performs cogent according to stats , not just cause they have a massive eye ball network in Europe.

Not end user ISPs , hosting companies aka content providers, and when there selling bandwidth cheaper then it costs to peer then there going to keep there costs to the minimum ... Cheaper is cheaper , the saying is true , you get what you pay for.

For a regional ISP looking for GigE ports in the Chicago/St. Louis area, is Cogent a reasonable solution? Our gut feeling is that they don't stack up against a Level3 or Sprint, but they are being very aggressive with pricing to try and get our business.
