We're not talking about a /24 or longer prefix here.  Based on the amount
of ARIN space Pegasus has and claims they've made, I'd guess they must
have somewhere in the neighborhood of a /16 worth of NAC space, probably
in several blocks of /24 and shorter.

So, how do your filters tell the difference between these broken out
NAC routes through a new provider and "multihomed customer routes with the
primary provider's connection down"?
