My application is a large-ish streaming video and file download service,
where I want to be able to automatically report on netblocks that are
seeing unusual packet loss, and then use that data to alert our NOC
and subsequently kick my transit providers with.

Determining optimal routing within the internet is a somewhat of random
process, and a lot of ISPs just always use the route with the shortest
AS-path even though a lot of times that turns out not to be the best
path at all (in terms of latency/loss.)
