Just to reply to Kelvin's comment, as discussed on IRC, manually applying the ingress yaml restores service, as does updating juju config to retrigger a pod-spec-set. So there is a workaround to this issue to restore service in case of an outage, but the question remains as to why it's happening in the first place.
