DNS Record for Amazon.com Dissapears

[eris0xff]

Hi all.  I'm running version OPNsense 22.1.4_1-amd64 and something strange happened this morning.  I woke up and all queries to amazon.com or any subdomains (as welll as other owned domains like imdb.com) came back with an empty A record.  This only happened with amazon records.  I have unbound DNS service running.   Once I rebooted opnsense everything was fine again.  Anyone familiar with this problem?  I've attached my unbound config and dig responses.  Thanks.
