I used to work for Keynote Systems and the hot potatoe routing was of major concern to customers. Many times you see inbound and outbound routes are significantly different due to the "least cost" associated with dollars in a peering relationship. You can see basic peering times from one of their public service sites, Internet Health Report. You can also do a quick one-off measurement from their demo site My Keynote. Check out the diagnostics tab and run some traceroutes from different backbones and you will immediatly see how congestion at major peering points can effect performance.
