> This is a method of the [**FleetSupervisionPolicy**](../classes/FleetSupervisionPolicy) class in the [**protocols**](../modules/protocols) module.

Trip the breaker when too large a fraction of the fleet is failing.

A systemic fault often shows up as many channels simultaneously in a
failing/parked state rather than as a raw restart rate. When at least
`failing_channel_fraction` of the fleet is failing, trip and start the
cooldown.

</ParamField>

<ParamField query="now" type="float" required={true}>
