We have version 1.3.4 on a server and have an odd, intermittent, problem
with looking up a particular record.
We have other unbound and bind servers that don't have this problem.
eg:
[root@a log]# unbound-control flush farnell.com
ok
[root@a log]# dig uk.farnell.com @localhost
That domain seems broken, at least from the "world view":
[paul@bofh ~]$ dnscheck uk.farnell.com.
0.000: uk.farnell.com. INFO Begin testing zone uk.farnell.com.
with version 1.2.1.
0.000: uk.farnell.com. INFO Begin testing delegation for uk.farnell.com..

If it works internally, perhaps one issue is that one of your
servers uses the external instead
of internal view?
Works fine here:

Any nothing obvious wrong?
