yes, they actively look for better paths (lower latency + packet loss). Mostly this is related to the path between the nearest CDN node and the DNS resolver that the end user is using. For this reason, it's a good idea to use in-house DNS resolvers for customer and it's a bad idea to have customers use 8.8.8.8, opendns and other public servers. If the BGP network you're talking about is concerned by the cost of doing this over VM / the tier2, they should look at whether a connection to an IXP would reduce their costs. Nick
