Unexpected Downtime

What is DNS Monitoring? +
DNS Monitoring tracks your domain’s DNS records and alerts you instantly when changes occur. This helps you detect misconfigurations, unauthorized changes, and potential outages before they impact users.
Which DNS records are monitored? +
Vigilant monitors all critical DNS records, including A, AAAA, CNAME, MX, TXT, and NS records, so you always know when something changes.

Alerts are sent in near real time as soon as a DNS change is detected, allowing you to act before downtime or traffic loss occurs.
