I tend to disagree. See with 25 RIPE Atlas probes:

With Google Public DNS :

% blaeu-resolve -r 25 --nameserver 8.8.8.8 instagram.com
Nameserver 8.8.8.8
[ERROR: SERVFAIL] : 14 occurrences 
[TIMEOUT(S)] : 9 occurrences 
Test #12294276 done at 2018-04-24T12:46:17Z

With the default resolver (sometimes Google Public DNS, sometimes not):

% blaeu-resolve -r 25  instagram.com
