registry.consul.register.deregisterCriticalServiceAfter configures the time the service health check is allowed to be in state critical until Consul automatically deregisters it. If fabio is still running, the service will be re-registered almost immediately after being deleted by Consul.

At the time of this writing, Consul enforces a minimum value of one minute and runs its reaper process every thirty seconds.

The default is

registry.consul.register.deregisterCriticalServiceAfter = 90m
