Sometimes a heroic emergency effort is required. As long as it is (extraordinarily) rare, it's not in itself sign of a dysfunctional organization.
Completely agree that it'something required sometimes. But it's nothing heroic, it is a (temporary I hope) dysfunctionment, and shouldn't be put in midly positive light.
Planning failed (not assuming you might have 2m users is sensible, but it's still a failure in it's way), and shit hit the fans. It's the kind of failure you might wish you had, but next time you should think hard about a way to deal with this kind of situation with minimal emegency, and no need for 'heroes'.
