DNS Monitoring and Troubleshooting

Use Exomonitor DNS monitoring to be alerted about DNS changes

Domain Name Server records are human-friendly names that point to internet addresses in various ways. Your users rely on DNS records, and your internal servers rely on DNS records. When something changes, you need to be alerted.

DNS quietly is the cause of many system issues, so an update on changes can solve many sorts of problems.

Common causes for DNS outages

There are many possible causes for a DNS outage:

1. Domain expiration or transfer: Your domain expired or was transferred or changed. (Are you monitoring your domain?)
2. Name server outages: Name servers are typically highly reliable, but even the most reliable name servers have gone down. You can use our port monitor to monitor it for outages. If there is an outage you should check the status page of whatever DNS service you use.
3. DNS misconfiguration: Records can be deleted or changed, by accident, by a person or a system. It's helpful to see the before and after to troubleshoot issues.
4. Security breaches: Hackers can often gain control of your DNS to cause security problems or a service outage. Having an immediate report would be a helpful way of immediately detecting the hacker. Always secure your DNS server and give minimal access and use MFA.

You should monitor your DNS and get a report on the DNS changes of your system.
