[Rant] Comcast\Level3 routing

Can someone please tell me why Comcast and Level3 are being retarded. The server I am trying to end on is in Atlanta. I am outside of Atlanta. My traffic goes from Atlanta to Chicago via Comcast then hops on L3 and heads from there to megapath and then megapath routes it finally back to Atlanta.

This has been like this for months. Anyone know who I can talk to to complain about this?

The site you are connecting to buys its connection and bandwidth from megapath, and megapath elects to peer with L3 in Chicago. Megapath does not have a circuit from Atlanta to Chicago.

Edit: Their route map does not show a direct path. Obviously there's some kind of connection.

Nothing to do with Comcast. If Megapath wants to meet their conditions and pay the price they can peer with Comcast.

Comcast and Level3 both route through Atlanta. Why would Comcast go to Chicago to route to Level3 in Chicago just to come back to Atlanta? This recently changed. Previously it was direct and never went outside of Georgia. Unfortunately I do not have any logs from this...

Google 69.12.54.12 and you'll see hundreds of similar complaints for at least a year, from users with all sorts of ISP.
Ask whoever runs 69.12.54.12 to switch or add other hosts.
Because comcast has to send the traffic to the advertised route which appears to be CHI right now.

Here is a trace from Windstream.

Level3 here takes it to Wasington DC where it then hands it over to Megapath.

Also saw this on »www.peeringdb.com/view.php?asn=4565

"Megapath is currently merging with Covad (AS18566) and Speakeasy (AS23504)"

So routing is gonna be changing.

I hope it will stabilize sometime soon. It is kind of ridiculous.

This has nothing to do with Comcast. Megapath/COVAD/Speakeasy (LOL!) doesn't peer with Level3 in Atlanta.

Easily verified with Level3's looking glass.

Keep in mind, Level3 is a Tier I so it's Megapath who is paying for connectivity to Level3. They're choosing not to, so your beef is with Megapath.
