We are happy to announce that we have added a new option to the check retries. 

You are now able to select 0 retries as an option.

When adding a new check or editing an existing check,  the Advanced tab includes an option to set the Number of Retries.

You can now select 0, ensuring that the probe reports a failure as soon as the first outage is detected.

For more information, please read our documentation on check retries.
