Comment:
Became concerned awhile back that even the brief time in state
`All nameservers have failed`
is harmful. Reviewed the code and determined that when only one
nameserver is configured nothing happens as a consequence of the state.
Outstanding requests complete successfully and the only effect is
`/var/log/messages` noise.
In the case where multiple nameservers are active, outstanding resolver
requests on the path where the `Bad response 5` appears are cancelled /
ignored and resubmitted to a different name server. Somewhat disruptive,
especially when resolvers are remote instead of local.
In the case where a local copy of `unbound` is running, stick with one
`/etc/resolve.conf` entry as configuring a second will degrade
performance.
