• I don't see why [DNS timeouts] it can't be long lived, but even normal TTL's would get amortized over a lot of connections. Right now with certs it is a 5 message affair which cannot get better. But that is why one of $BROWSERVENDORS doing an experiment would be helpful.

There are use-cases where a five-second DNS TTL is important.  And they’re not amortized over multiple connections from *one* user, but rather affect *many* users.  Imagine an e-commerce site connected to two CDN’s who needs to switch.
