I feel your pain Bill, but from a slightly different angle. For years the large CDNs have been disregarding prepends. When a source AS disregards BGP best path selection rules, it sets off a chain reaction of silliness not attributable to the transit AS's. At the terminus of that chain are destination / eyeball AS's now compelled to do undesirable things out of necessity such as: 1) Advertise specifics towards select peers - i.e. inconsistent edge routing policy & littering global table 2) Continuing to prepending a ridiculous amount anyway Gotta wonder how things would be if everyone just abided by the rules.
