what's considered to be the smallest v4 block which would be globally routable given BGP prefix filtering?/24 isn't it?
We announce a /24 of PI space on behalf of one of our clients and periodically (although not frequently) they find places they can't reach due to aggressive prefix filtering. But on the whole it seems completely usable.
I would expect a /25 to be a very different story though.
