So in practice until page reload, right?

Why are DNS errors different from under underlying network layer errors 
here?  For example, when using a proxy, you'll never actually get 
"useful" DNS errors, since the only thing you resolve is the proxy.  So 
it doesn't make much sense to me to special-case DNS errors...

Also, that still leaves the question of 2xx responses that aren't 
explicitly mentioned in the spec.  Those should be treated as 200 in my 
opinion.
