AT&T routing issue

Hi all, We have recently brought up some BGP sessions with a new provider, and have found that we can get end to end connectivity through the new provider to pretty much everywhere except networks behind AT&T (AS7018). We are able to see our routes in AT&T's route server, but all traceroutes from our network to hosts behind 7018 stop at AT&T's border. We are multihomed, so I've local-prefed up our secondary ISP and the problem resolves immediately. Our upstream (AS9443) and their upstream (AS11867) have been chasing this up with AT&T for a couple of days, but don't seem to have had made much progress. Does anyone have any suggestions as to what could be causing this, or a contact at AT&T who might be able to assist? Thanks, Alex
