I like it because it provides a socially acceptable excuse to tell other people to GTFO and let me focus. Otherwise, I tend to be distracted by requests from other people. Often imagined ones. It's really probably just me who needs to convince myself that yes, I can say "no", and yes, I can stop thinking about every other obligation and expectation while focusing on the task at hand. A crisis temporarily eliminates this entire problem.
We just nominate a central person for contact during emergency and they have to deal with the communication, then rest just updates the status of the outage to that person.
