A client of ours recently had a major business announcement and needed to update their site's theme and publish a node to coincide with the announcement. Had the announcement been scheduled for regular business hours I probably would have made the changes manually, but because it was scheduled for 5:30 am I needed a better solution.

First I tried talking a few co-workers into finally learning how to work with git tags on a live site, but that didn't go very well even without mentioning the 5:30 am bit.
