Know when a DNS record changes or stops resolving

A wrong or missing record breaks email, sign-in and websites at the same time. A DNS monitor resolves one record type for a name and can compare the answer with the value you expect.

Set it up

Check that mail still goes to the right server:

Type:        DNS
Name:        example.com
Record type: MX
Expected:    10 mail.example.com

How it checks.

Record types: A, AAAA, CNAME, MX, TXT, NS and SOA.
An optional expected value; a different answer counts as down.
The domain’s registration expiry is checked too.
The alert names the monitor and says the answer did not match or the name did not resolve.
