We can and should unwind this setup now David. Our transit bandwidth situation has improved greatly since we set that all up and we don't need any help.

When I get into the office later today I will add a couple prepends then turn down that BGP session. We can chat offline about it if needed otherwise, David.

Thanks.

I realize that the return traffic might be taking a different route, however one of the MICE members still needs to be transiting it to Charter.  I guess it may just be an inevitable side effect of providing the internet connection to fill the cluster.

I can assure you the path from Akamai to Charter is not following that path, this is an asymmetrical path.  We are helping USInternet provide cache fill for Akamai by announcing the prefix through commercial peering relationships we have.  Along with cache fill comes some TCP Ack traffic depending on some people's routing policy.
