failureThreshold

The number of consecutive health checks that an endpoint must pass or fail for Amazon Route 53 to change the current status of the endpoint from unhealthy to healthy or vice versa. For more information, see How Amazon Route 53 Determines Whether an Endpoint Is Healthy in the Amazon Route 53 Developer Guide.

FailureThreshold is not supported when you specify a value for Type of RECOVERY_CONTROL.

Otherwise, if you don't specify a value for FailureThreshold, the default value is three health checks.
