DNS monitoring: catch the change that breaks everything at once
A wrong DNS record can take down your website, your email and your API in one edit, and every other monitor will just say “down”. DNS monitoring checks that your records resolve to the values you expect, and tells you the moment they change.
Illustrative example
DNS monitoring regularly queries a domain’s DNS records and alerts you when the domain fails to resolve or when a record, such as A, AAAA, CNAME, MX or TXT, no longer matches the expected value.
Why DNS deserves its own monitor
DNS failures are rare, fast and total. They usually come from a human change: a migration, a new email provider, a record deleted during clean-up, an expired DNS provider account. Sometimes they come from someone else entirely, like a hijacked registrar account. Uptime monitors only tell you the site is unreachable. A DNS monitor tells you why, and catches changes that don’t break the site but break email deliverability (SPF, DKIM, DMARC).
Records to watch
| Record | What breaks if it changes | A / AAAA | CNAME | MX | TXT (SPF, DKIM, DMARC) | NS | CAA |
|---|---|---|---|---|---|---|---|
| The website and API stop resolving to your servers | |||||||
| CDN, status page or SaaS custom domains stop working | |||||||
| Inbound email goes nowhere | |||||||
| Outgoing email lands in spam or gets rejected | |||||||
| Someone moved your DNS. Treat as urgent | |||||||
| Certificate renewal can start failing |
How StatusEagle DNS monitoring will work
Until DNS monitoring ships, a UDP check on port 53 confirms your nameservers answer, and domain monitoring covers registration expiry.
