Don’t you hate it when your computer gets all bricked up?
You can help keep things regular just by adding a little fiber to your network.
If that’s not an option, open a tab to metamucil.io and download a couple packets twice a day.
Or the router, in another state, and the person with access to the closet/server room knows how to push a few buttons at best.
That happens once… and you get misconfigophobia for life.
FYI with many routers, switches, and firewalls there are ways to automatically rollback changes in case the device is unreachable after applying them. Usually the command is called something like “Rollback”.
You usually supply a time limit when you run the command and if you don’t confirm the changes before that time limit it will rollback. So if you run rollback 30 and then do something which breaks the network connection, the config will rollback in 30 seconds. If it does work, you simply cancel the rollback.
