DNS monitoring that can verify the record you expect
UptimeSure resolves the DNS record type you configure and can compare returned values with an expected value. It is designed to catch missing, failed or unexpectedly changed DNS answers without claiming full authoritative-DNS analytics.
A DNS monitor queries one domain and record type using the checker’s DNS resolver path. Optional expected-value matching lets you turn an unexpected answer into a failed check.
Resolution failure, missing expected answers or an expected-value mismatch produces DOWN according to the checker contract.
Results feed the same confirmation-threshold and incident pipeline used by the rest of UptimeSure.

Frequently asked questions
Is this a DNS propagation map?
No. V1 is a single-location DNS monitor, not a global propagation service.
Can I verify an expected answer?
Yes, for record/value combinations supported by the DNS checker contract.
Does UptimeSure operate my DNS?
No. It monitors DNS behavior; it does not manage your DNS provider.
