I remember the first time I got access to an employers production Cisco router. It’s pretty scary how easy it is to majorly fuck something up.

There isn’t a concept of a transaction or a rollback. You just enter a command, press enter and it’s live.

To counter this we’d write all the commands we planned on executing and peer review it. Nothing was to be done “on the fly” (at least in theory)

In short, coming from a developer perspective with ample version controls and gated releases… networking is a very wild ride.
