It just means "do nothing" (including not automatically retrying). If the

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.
