I suspect most people who've ever been responsible for colo-ed unix-ish servers have learned to do something like:

> ufw reset | at now +5 minutes

When doing "dangerous" things like updating firewall rules.

I wonder if they have a way to send commands saying something like:

Switch to thruster set 1, wriggle the antenna aim away and back to earth, wait 46 hours, if you do not receive "all clear" from earth switch back to thruster set 3 and re aim the antenna at earth.

So obvious! But _no_ I haven't done this even though I have messed up remote servers where this would have helped. A bit embarrassed I didn't think of it myself, but thanks for the tip nonetheless!

I also did not think of it myself, but had it shown to me by a greybeard after complaining about having messed up in exactly that way, and had to pay extortionate prices for "hands on" by someone at our colo facility...

No I just always have a serial console and a power switch which are not affected by anything I can do on that box.

I still fuck them up after 20 years.

Fortunately we have ILO / RAS cards in everything.
