The best question is: Do you know what prefix you just lost reachability to, or do you just point default as a last resort anyways, so don't know.
One has to wonder how many places are using the prepend-me-harder commands to do traffic engineering, and have absolutely no clue that their prepends are having the opposite effect because the prefix is being dropped entirely by some AS's. I suppose the exact same issue applies for those places that deaggregate in an attempt to to TE, and the de-aggregated prefixes get munched by somebody's prefix-length filter.
