The public resolvers return different records for the same question.

DNS_ANSWERS_DIFFER · Severity: Info

• InfoDNS_ANSWERS_DIFFER

  The public resolvers return different records for the same question.

  The resolvers agree on the response code but not on the records. CDNs, load balancers and geographic DNS answer differently by design; after a change it can also be an old cached answer. TTLs are not compared. The evidence lists the records only one resolver returned.
