On: It's always TCP_NODELAY

[jcgrillo]

Configuration changes are one of those areas where having some kind of "are you sure? (y/n)" check can really pay off. It wouldn't have helped in this case, because there wasn't really any change management process to speak of, but we haven't fully learned the lesson yet.

Confirmations are mostly useless unless you explicitly spell out the implications of the change. They are also inferior to being able to undo changes.

That's a lesson many don't know.

Your time from commit to live is proportional to your rollback to a known good state. Maybe to a power of the rollback time.
