On the morning of July 17, a redditor who normally pays Amazon Web Services about five cents a month opened their inbox to a wall of billing alerts and a running tab of $2.5 billion. Their whole setup was a single S3 storage bucket, untouched since 2023 and not even public. "What should I do?" they asked r/aws. "Is there any way to escalate this urgently?"
They weren't alone. Across the thread, other AWS customers reported the same overnight sticker shock — forecasts of $5 trillion, an estimated bill of $2.5 trillion against a $3,000 budget, an alert for nearly $700 million on an account capped at $10. One user got so rattled they closed their account. It was, as people soon worked out, a billing glitch that AWS acknowledged on its own service-health dashboard.
Best comment: "Remember, if you owe someone $10k that's your problem…but if you owe them $1bn that's their problem."
