Bunny DNS provides basic built-in monitoring for any added A, AAAA or CNAME record by default. This document contains information about the monitoring system and answers to common questions.
When is a record marked as offline?
For every test, 1 request is sent from a selection of 3 regions around the world to a monitored IP. For a record to be detected as online, the monitored response should be successful.
How frequently are records monitored?
The basic monitoring in Bunny DNS tests each IP every 30 seconds. It is currently not possible to change the monitoring interval.
What monitoring types are available?
With basic monitoring, two monitoring types are available:
- Ping - Ping will use an ICMP ping packet to monitor the availability of a record. During a test from one region, 4 packets are sent. For success, at least one packet needs to be successfully returned within 2500ms.
- HTTP - HTTP monitoring will send HTTP requests to the configured IP on port 80 to determine if the record is available. The request needs to complete within 10 seconds and the HTTP status code response must be a non 5xx response, otherwise the response is counted as a timeout.
Can I set up alerts when an outage is detected?
Currently, Bunny DNS is not able to send alerts when an outage is detected, however, this will be added in the future.
What happens if a record is detected as offline?
This depends on the number of records within the group. If the record has a single value, nothing happens and the system will continue to return the record value. If the record is part of a group of DNS records with the same type and domain, offline records are removed from the routing.
