An excellent explanation, clear and concise.
However, outside of a technical audience, you might struggle to find an audience that understands it.
Explaining the technicalities of how the Internet (or indeed technology in general) works is a complete turn-off. 99.9% of people don't care .... and nor should they. They turn on their phone, tablet or computer, and use the Internet. That's it. Simples!
Having worked for technology companies since the mid-80's I can safely say that the IT industry - together with the people who work in it - are frequently their own worst enemy. We use language, concepts and terminology that might as well be written in Cyrillic, for all the sense it makes to everyone else.
That's also why, outside of the world of IT nerds and geeks, no-one is getting excited by the fact that this week's outage was caused by "DNS resolution of the DynamoDB API endpoint in US-EAST-1".
Although it might skip a few details, if explaining that what caused the problem is that AWS lost its map of the internet, it gets my vote. Even Mrs G can understand what a map does!
The more important takeaways are that AWS is not the Internet, the Internet was not "broken", and - from the root cause analysis - the problem was technical in nature, and not caused by a cyber attack.
