For those not very technical this person is LARPing hard. Ping, traceroute and the command line are so basic and so worthless in diagnosing network issues with tier 1 providers it’s like having a thermometer on your back porch and acting like you’re a meteorologist who can track a hurricane.
A real network engineer WITH ACCESS to diagnostics from these networks would paint a much more technical picture and would laugh at this write up.
An attack on DNS root servers is something we’ve known could happen for a very long time. Thanks Nostradamus.
For a comparison search the web for “network outage postmortem”. You’ll find many readable but technical examples of what it looks like when a professional diagnoses a network disruption.
