DNS Monitoring & Record Checks

DNS monitoring resolves your domain on a schedule and checks the answers, so you know your records are correct, resolution is fast, and nothing has changed without your knowledge.

You can monitor A, AAAA, CNAME, MX, TXT and NS records, with assertions on the values each record returns.

Yes. Assert that a record must equal or contain expected values, for example this A record must equal these IPs, and any unauthorized or accidental change fails the check and triggers an alert.

Checks run from 25 cloud regions, so resolver-specific problems and regional propagation delays become visible instead of hiding behind a single location.

Yes, DNS monitors are available on the free plan and count toward the 10-monitor free allowance, with 5-minute frequency on free and 1-minute on paid plans.

You receive alerts on failure and on recovery via email, Slack, Microsoft Teams, webhooks, Discord, PagerDuty and Opsgenie.

Uptime monitoring tells you a hostname stopped answering. DNS monitoring tells you why, by watching the records that resolve that hostname in the first place. A server can be perfectly healthy while an A record points somewhere wrong or an MX record disappears, and only a DNS check sees that.

Mail delivery depends on records that live in DNS, so monitoring MX and TXT records catches the failures that silently stop email. A dropped MX record stops inbound mail, and an edited SPF or DKIM record in TXT quietly moves your outbound mail to spam. A record-value assertion alerts you when the value changes rather than only when it disappears.

No. LoadFocus checks your DNS from the outside, the way your users resolve it: it queries your records from the regions you choose and checks the answers and the resolution time. Nothing is installed on your DNS server, and its query logs are not read.
