check / check (push) Canceled after 0s
The resolver lists in FailedTypes each record type whose query to a nameserver got no usable reply (none after two tries, an error reply, a referral, or a truncated reply whose TCP retry failed), and logs it with the reason unless shutdown cut it short. A nameserver that answered no type has failed, as before. The watcher saves such a type in failedTypes, keeping the previous check's records, leaves it out of the comparison with other nameservers on that check, and compares the kept records with the next answer. With nothing to keep, it is also in unknownTypes and not compared until it answers. Change messages leave out what was not compared. A nameserver whose A, AAAA or CNAME query failed is no answer when following a CNAME or resolving addresses. Model: opus-5-5
