> I'd be okay if we just did this at latest time we could fetch a new
consensus. How hard/bad would that be?
Hm, when is that I wonder?
Clients download a new consensus every 1 hour, right? If yes, the latest
time that an always-on client could have fetched a consensus would be its
`valid-after` time + an hour? Or the time its published + an hour, if
that's a different thing.
> (And what's the harm of using an IP that's not in the consensus anyway?)
Hm, good question.
I guess the main issue is that clients with a newer consensus won't be
able to use that IP. Or maybe the IP was found to be a bad relay?
(There are not many nice attacks that IPs can launch right now, but maybe
that will change in the future when we introduce scalability etc.)
