AWS billing glitch showed some customers estimates above $3 billion

Amazon Web Services said a display bug in its estimated billing tools caused some customers to see projected cloud charges ranging from billions of dollars to the trillions and, in a few cases, the quadrillions. The company said the problem was limited to estimates shown in billing dashboards rather than actual invoices, and reiterated that no manual action was required from customers. AWS Support said an initial rollback did not immediately resolve the issue, with technical teams continuing to work on corrected figures. The malfunction stemmed from a faulty calculation in AWS’s estimated billing subsystem that multiplied normal usage into extreme totals. The episode added to scrutiny of AWS’s operational resilience after a May data center outage disrupted trading at Coinbase. It also landed during a broader stretch of high-profile automation and display errors across major platforms, including a Bitcoin price display glitch at Revolut and criticism of Coinbase over an AI prediction market error that showed a false World Cup result. Because AWS is a core provider of enterprise and internet infrastructure, the billing anomaly drew attention beyond its direct customer base. The company also struck a $6 billion AI infrastructure deal with Snowflake in May, underscoring its scale. AWS’s official X account responded with humor, calling the problem a typo and a “slight miscalculation,” while stressing that only estimates were affected and accurate dashboard data would return soon.
