RBL timeouts
Hi,

Is anyone (everyone?) also experiencing DNS timeouts with barracuda?

02-Dec-2022 07:03:02.229 query-errors: client @0x7fd19d26c968
127.0.0.1#37098 (168.22.111.13.bb.barracudacentral.org): query failed
(timed out) for 168.22.111.13.bb.barracudacentral.org/IN/A at
../../../lib/ns/query.c:7729
02-Dec-2022 07:03:21.458 lame-servers: SERVFAIL unexpected RCODE resolving '
216.209.245.104.bb.barracudacentral.org/A/IN': 3.13.7.254#53

I'm also seeing a few timeouts from mcafee:

24-Nov-2022 16:12:37.151 query-errors: client @0x7fd19f7a4f68
127.0.0.1#47466 (17.31.10.37.cidr.bl.mcafee.com): query failed (timed out)
for 17.31.10.37.cidr.bl.mcafee.com/IN/A at ../../../lib/ns/query.c:7729

I don't necessarily think there's something wrong with my nameservers - I'm
more just surprised that such high-profile companies are having problems
and wanted to confirm.

Any bind experts know of a way to record which nameserver is timing out so
I can perhaps exclude them? Any idea why it wouldn't just rotate to the
next one, or even how to confirm whether it's doing that?
