We could break our prefixes into smaller routes, but 1) the Internet's routers have limited memory; 2) we have a lot of routes; and 3) we want to be good Internet citizens.

If every network announced all their routes as /24s — the smallest route generally accepted over the public Internet — the routing table would be a giant mess and would overwhelm many routers' ability to store them.

That said, after today we are thinking about ways that, in case of an emergency, we could break the routes down to be more specific than whatever is leaking. Given how broadly peered we are, Cloudflare's network will be as protected as anyone's. However, that's not really a good solution for the Internet generally. Better that we all implement and enforce RPKI.

Kudos for a CEO that understands in and outs of Internet routing, making me want to join CF's neteng team

Kudos for not deaggregating routes into /24s like many other major ISPs do nowadays.
