Comment (by arma):

 Ah ha -- this isn't a time issue, it's an issue of whether that dir
 authority has a consensus it's willing to give you.

 This response from dizum was added in #20511.

 And it could plausibly come from a dir auth that's been down for a while
 and then comes back and doesn't have a fresh consensus to serve quite yet.

 I think teor is right that there's nothing the relay operator can do when
 this happens. I'm tempted to wonder if we can move it to info, since
 notice will still make some people worried. But on the flip side, I'd only
 want to move it to info if we're confident Tor will always tolerate the
 situation well.
