Look at this as a handy guide to how not to deploy in one single page. Pretty much any of the things in bold, had they not been done, would have avoided this from happening. Reused flags, letting dead code sit around in production for years, lack of change management, etc, all are signs of something gone horribly wrong. Also, regardless of if the deploy went good or bad, discuss the aftermath with co-workers. I'd almost guarantee that some of these problems had crept up before, and being able to ask the question of "how can this never happen again" is important, because otherwise, those problems will be forgotten and stumbled over again, in a future, perhaps more critical incident.
