This page describes the notification options available in DNS Check. Notifications are sent each time a DNS record changes state between untested, passing, and failing, unless one of the following conditions is met:
- The DNS record was just created, and its first test result was a pass
- Notifications are disabled for the DNS records group
- The transition is to Failing, but the failure is a suppressed ServFail error
Emailed Notifications
To enable emailed notifications:
- Go to your Notification Settings page.
- Click the Email tab.
- Select your desired notification frequency, then click Save:
If the Immediate option is selected, DNS Check will email you a notification immediately after a DNS record changes state between passing and failing.
If the Hourly digest or Daily digest option is selected, then emails are batched so that you'll receive no more than one email about DNS record changes per hour or day, respectively. For example, if 10 DNS records change state between these digests, DNS Check will list all 10 state changes in a single email.
Notifications are emailed to the email address in your account's profile.

ServFail Errors
Most of the DNS errors that DNS Check detects are ServFail errors. ServFail errors indicate an error communicating with the DNS server, not an issue with the data it returned. You can configure how quickly DNS Check notifies you about ServFail errors by editing the "Suppress notifications for up to X consecutive ServFail errors" setting in your Notification Settings page:
