Not that I havee actually seen this problem because we don't buy transit from MCI, but... You may want to try adding a few additional copies of your AS to your MCI advertisement "prepend as 65536 65536 65536" where 65536 is actually your AS. It largely depends on _how_ PSI is implementing their policy. It could just be that all routes learned from their West Coast router (i.e. a Border Router) are given a lower priority than private connect routers. I guess a PSI person would be much better at answering with specifics. I know I have seen customers get traffic flows to jump through the most insane paths just be adding god awful AS lengths to their announcements. Hope it helps, -Deepak.

Is anyone else having routing problems with PSI?
On the left coast, we peer with PSI. We buy transit from MCI. PSI recently (about a month ago) installed a broken localpref to prefer their private MCI connection. It doesn't matter what we advertise to MCI (double-hop, origin incomplete), PSI still uses their private MCI peering - which of course is full during the day, so PSI customers get packet loss.
Naturally, the problem does not exist on the right coast :-)
I've called the NOC about 20 times now, trying to get it resolved. I've been promised, multiple times, that it would be fixed, only to get told today that "it's a policy issue". What? :-(
Anyone else having trouble?
