DNS Health Check

You can turn on DNS Health Check when adding or editing DNS records.

The following meanings apply to the configuration options:

• Port: Edge Admin will examine whether the IP + configured port of a DNS record posts normal communication. Only one port is allowed to be configured for each DNS application
• Timeout period: Examine the TCP connection timeout every time. If a normal connection cannot be established within the specified time, the examination result will be marked as a failure.
• Threshold: The DNS record will be deemed unhealthy if the times of failure spotted in examination exceed this threshold.

Health check is temporarily applicable only to DNS records of A and AAAA types. Unhealthy DNS records will be compulsorily taken offline.
