Had a node that I was connected to over wireguard. Wanted to reset the wireguard conf.

Nice one, mate. Had to drive back to log in and bring up that interface. I still do this, FWIW, but now I use `at` to schedule "up" 1 min in future haha. So far so good though it's not smart :)

Luckily for me, I just had to go down the hall to the data center, and then reset it with the local terminal. Compared to you, I learned the lesson on the cheap, but you got the bonus of a nice get out of jail free card. Neat CYA trick that I will keep in mind.

There's a feature in many business data centers called "remote hands". Mainly to avoid the drive/flight to admin a remote machine.

Any time I’m ever doing a pfctl to change my router’s firewall rules I schedule a “revert to the n-1 rule set” job two minutes from now to avoid the trip to the basement & hunt for the serial cable.

I do +2 because once I was too close to the next minute, fat-fingered the update command & instinctively corrected it. But the change had reverted before I hit enter on the new update, so of course I blocked too much traffic and wedged my SSH connection, triggering the cursing and trip to the basement with the serial cable.
