France won the World Cup, 4-2 over Croatia in the most entertaining final in decades, Mbappé (19!) scoring like the future arriving on schedule, while Croatia (population four million, playing their third consecutive extra-time-adjacent epic) won every neutral heart including this office’s entire non-French contingent. And the Thai cave rescue worked: all twelve boys and the coach, out alive, via an operation (anesthetized kids, dive relays, a former Thai Navy SEAL who gave his life placing tanks) that will be studied by every high-risk-operations community forever. The fortnight the whole world got two good endings. The archive requires me to note when the news is good; it’s rarer than outages.
Meanwhile, on the day Amazon engineered to be its biggest shopping event of the year: Prime Day crashed. Error dogs (“the dogs of Amazon”) greeted shoppers for hours at peak; internal reports later suggested the auto-scaling couldn’t keep pace and manual server adds were happening during the event. The company that wrote the book on elasticity, whose cloud the rest of us buy specifically for this problem, got thundering-herded (drink) by its own marketing calendar.

Predictable is not provisioned.
