DNS Monitoring

Resolution that works — and returns the records you expect.

A DNS monitor resolves a name against a public resolver from each region and can require the answer to contain specific values, so a hijacked or silently changed record is caught, not just a lookup failure.

DNS monitor dashboard: uptime overview, response time percentiles, SLA status and DNS answer counts

What it detects

  • A name that stops resolving
  • Records that no longer match the values you expect
  • Slow lookups
  • Missing or changed SPF, DKIM and DMARC records (see Email Authentication)

How you're alerted

  • Create an alert rule on the DNS result, or use a TXT expectation as an always-on check.

Notifications go to any of 8 channels — see notifications.
