While I agree generally, it's a bit unfortunate that we can't (as a

special-casing things and presumably that would open a whole can of worms.

Really what is the difference between a cable cut and what you are
doing ?

Some frames are lost (Dropped), and sender doesnt 'know' that is
definitive or temporary failure.

If you want faster response, you need to send RST messages, not dropping
frames.

So change your strategy, and add an iptables rule for example ?
