> Back when a 100 nodes was a "big" network these sorts of problems were so rare that you could be forgiven for not taking them into account Not really. Writing reliable network programs always had to take this into account. Take the scenario (not mentioned in TFA) where a firewall somewhere in the network path suddenly starts blocking traffic in one direction. Or handle a patch cable being pulled from a switch (or from your computer which has a different result). These scenarios always were real and resulted in comparable connection error states. Do agree it's a good post though, explains it rather nicely.
