I'm fairly certain the forwarders aren't the problem since I run those
as well.  They are standard BIND 9 installs running full recursion
with no firewall on the DNS traffic, but they don't have DNSSEC
validation turned on yet.

Too late to check--it is working now with the same forwards.  So this
was a transient issue.

# host bugs.debian.org
bugs.debian.org has address
bugs.debian.org has address
bugs.debian.org has IPv6 address 2607:f8f0:610:4000:6564:a62:ce0c:138c
bugs.debian.org mail is handled by 10 buxtehude.debian.org.

I have very few issues with unbound/DNSSEC, so I'm not sure what to do
for troubleshooting when a problem does happen.  What verbosity level
do you suggest?  I'll have to leave it cranked up so I'll have the
data if/when this happens again.
