No, it's just mindless speculation from someone who clearly hasn't worked a critical service's on call rotation before. Not at all what it's actually like, all these services have automatic alarms that will start blaring and firing pagers, and once scope of impact is determined to be large escalations start happening extremely quickly paging anyone even possibly able to diagnose the issue. There's also crisis rotations staffed with high level ICs and incident managers who will join ASAP and start directing the situation, you don't need to wait for some director or VP.
