When I worked for a department that had a rotating on-call person, if they didn't answer the call, then it was escalated up the chain, and sometimes that in fact happened. Nobody was actually making $300K, I don't think, but still, management was effectively always on call, just with less odds.

Not sure if that's still the case, but a while ago as an AWS customer with premium support you got a very extensive list of phone numbers of AWS representatives to escalate issues to in case your technical account manager or his supervisor were not available in emergencies. While I believe the list didn't include somebody from AWS' C-level, it went pretty high up. As I customer that felt very good, because it gave us the confidence that there is always somebody available in case of emergencies.

Not technically on call, yet it takes about 20 minutes to get through the corporate officer titles on an enterprise bridge, making it hard to complete the reboot sequence within the Platinum response time.

We've reached a strange point where I can no longer tell if the above comment is genuine, satire, or schizophrenia.

It's like some crappy AI bot learning to interact with humans.
