Comment:

 Replying to [comment:2 atagar]:
 > Great, thanks David! Maybe we can provide a more helpful controller
 response? QUERY_NO_HSDIR indicates that we don't have a hidden service
 directory available. Not that we're being throttled, or what to do.

 There are two cases where you get `QUERY_NO_HSDIR`:

 1. Rate limited and no more are available from the set you can query.

 2. All of the HSDir do not have the .onion descriptor so you have no more
 to query.

 In both cases, they could probably benefit to have their own distinctive
 error code.
