DNS Check makes a number of notification options available to you. Each time a DNS record changes state between passing and failing, a notification gets sent using each enabled option. You may enable as many, or as few of these options as you'd like.
You can receive email notifications when DNS records start passing or failing. To enable this feature:
- 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 is found to have changed state between passing and failing.
If the Hourly digest or Daily digest option is selected, then emails will be batched, so that you'll receive no more than one email about DNS record change(s) per hour, or day, respectively. For example, if 10 DNS records change state between these emailed digests, DNS Check will list all 10 DNS record state changes in the same email.
Notifications are emailed to the email address in your account's profile.
You can integrate DNS Check with the following services to be paged when an issue is detected:
DNS Check can send notifications via the following chat services:
Most of the DNS errors that DNS Check detects are ServFail errors. ServFail errors indicate that there was an error communicating with the DNS server, and not an issue with the data that the DNS server 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:
