atlas.cogentco.com servers and bad reouting cause lagspikes

Barking up the wrong tree. SE isn't using Cogent Communications.... they use Ormuco. Your ISP has agreements with Cogent to carry their subscribers data across North America.

Now, if your traces are also showing issues in the Ormuco segments, SE may be able to assist there--but that is about as far as they can go to rectify it. Only other thing they can do is address issues with how the ISP's are identifying their packets. O2 found an issue with their packets that was preventing them from being identified properly... never did hear whether SE addressed that or not. Outside of addressing such concerns once they are identifed by an ISP or bringing up congestion issues with their provider (again, Ormuco and not Cogent), there isn't much SE can do to address an issue that is found with your ISP or your ISP's partners, unless they contact SE for information to assist them with the problems they found (like O2 did about 2 months back).

So basically, if you are only seeing issues on your ISP or their partner's segments (ie: Cogentco)--you need to be working with your ISP.
