They're pretty readable, I recommend that second one (though it leaves some questions I have unanswered). It's a good example of how latent issues with a large system can go unrecognised for a long time before a seeming unrelated change can trigger a cascading failure

> Each decision solved the problem in front of it. Nobody was asked to look at the sum of all actions.

This is the perfect description of Telstra as a company.

Author needs to decide which end of the stratum stack they want as the top.

> This design from 2010 had at the top stratum 1 sources at Australia's National Measurement Institute (NMI)

> Among otherwise comparable candidates, the lower stratum carries more weight.

It's funny, but I had the same thing happen to me once. One day, overnight, my computer decided it was 2006.

It happened twenty years ago...
