Here's a real example, using an organization that is listed publicly as

IN CNAME _dmarc.gcu.edu.dmarc.has.pphosted.com.
The record is correct at the time of writing, but if it's anything like
the others then it will intermittently return a blank TXT record that is
signed by DNSSEC.
And having done a lookup on the above record several times today, I can
confirm that for a short period it was returning missing values.
