AWS experienced a billing display bug Thursday evening that showed some customers inflated bills ranging from millions to billions of dollars, caused by incorrect unit pricing in the estimated billing system. Amazon confirmed the charges are not actual and paused estimated billing updates while reverting to accurate data.

That's a dependency risk — and a reason to build billing anomaly detection into your own platform before AWS does it for you.
