domain.monitor_updated

Fires whenever the runtime monitor signal changes — DNS started/stopped resolving, switched away from our edge IPs, SSL state shifted, etc.

This event is noisier than the other lifecycle events: it can fire even when the overall status doesn't change. If you only care about lifecycle transitions, subscribe to domain.verified / domain.failed / domain.expired instead.
