This is reproducible still with Juju 2.5.1 and maas provider with maas 2.5.0-7442-gdf68e30a5-0ubuntu1~18.04.1.

I simulated a dead Juju controller machine by suspending a MAAS Pod VM responsible for one of the controller, but Juju reports all controller nodes are healthy.

$ virsh suspend juju-1 ## simulate an unresponsive controller

$ juju ssh -m controller 0 ## 0 = juju-1
ERROR cannot connect to any address: []

$ juju status -m controller; juju show-controller | grep ha-status:

-> status doesn't report any down / unhealthy controller node even after 5 minutes.
