Among RIPE Atlas probes, most succeed:

% blaeu-resolve --displayvalidation -r 100  --type A gpo.gov
[ (Authentic Data flag)  162.140.14.82] : 46 occurrences 
[162.140.14.82] : 52 occurrences 
[ERROR: SERVFAIL] : 2 occurrences 
Test #50935448 done at 2023-03-14T15:46:50Z

The two whose resolvers servfail may have stricter/paranoid resolvers.
