In my experience, Good organizations have scheduled updates for critical outages. No one pesters anyone, and everyone knows that a five minute update is expected periodically, e.g. at the top of every hour. Great organizations instantly spin up a response team which includes a communications liaison, who is technical enough to participate in the reponse, but is not presently leading it. They assist and communicate, either to the PM or to customers directly. ...and other organizations burn through humans until they get a handle on how to be better. That said, in these days of AWS and GCE, you can go a loong time without running into the kinds of failures that used to cause critical, extended outages.
