[Unbound-users] Query over 'forward-addr' / 'forward-first'

I've just started looking at Unbound, under FreeBSD 9, currently running
I have three 'local' nameservers on our LAN, and I've been using:
[obviously 'example' IP's!]
This seems to work fine - i.e. under normal circumstances, queries are
answered fine. If I deliberately "fail" 184.108.40.206 - queries are still
answered, ditto if I fail 220.127.116.11 as well - they are all sent to 18.104.22.168 to
be resolved, and the system can still resolve names.
In 1.4.17 how are forwarders selected? - From syslog/verbose logging - it
appears it latches onto one, and stays with it (maybe the fastest
Is there any way of seeing (e.g. from 'unbound-control dump_infra') which
forwarders it considers 'available' or 'not available' / down?
Also, can someone clarify what 'forward-first' actually means? - In the man
page it says:
"If enabled, a query is attempted without the forward clause if
it fails. The default is no."
With this set to 'yes' - if I fail all the forwarders, nothing gets
resolved (I was kind of expecting it to retry the query - with the roots? -
i.e. no forwarders?) - or does this not apply if you're trying to forward
Thanks for your time,
