While I agree with you, I think the anecdote is still useful because it shows that the problems of the present are really problems of the past too.
Software quality improves, sure, but you can still learn from the past.

Our heartbeat links are segregated from the public network with separate network cards/switches. So the specific issue github hit here isn't what we would have encountered. We do have quad nic cards for a reason in the systems we run, this issue github hit is one of the various reasons you don't run heartbeat over the public topology. It will bite you in the ass no matter what cluster software you are running.
Unless you also have a disk heartbeat over shared fibre/scsi, or maybe serial but same difference. Depending upon the public network though is a lost cause.
