AWS billing glitch inflates customer estimates from cents to trillions

Amazon Web Services experienced a billing glitch that caused some customers to see dramatically inflated estimated charges, with monthly estimates skyrocketing from a few cents to figures in the billions or even trillions of dollars. The error, which affected an unspecified number of users, originated within AWS's billing system and was reported on Friday morning via the AWS Health Dashboard.

Amazon acknowledged the issue in a statement, reassuring customers that the inflated numbers were not representative of their real bills. The company identified the root cause within an hour and a half of starting its investigation, describing it as "an issue with unit pricing within the estima" according to Slashdot, which cited an open issue on the AWS Health Dashboard. The problem specifically impacted the Cost Explorer tool, which provides estimated billing data.

Some of the estimated amounts were staggering. According to The Next Web, a unit pricing error in AWS Cost Explorer emailed users bills ranging from billions up to $2.5 trillion. One user who typically had $0.19 in charges received a $2.5 billion estimate. Wired reported that the glitch caused monthly bills to rise from a few cents to billions, while BackBox.org noted that customers logged in to find estimates claiming they owed billions in fees.

As of the time of reporting, the issue remained unresolved despite AWS attempting several fixes, according to Slashdot. Amazon has not publicly detailed the exact cause of the error or confirmed how many accounts were impacted, as noted by ShortSingh. The company advised customers that the displayed estimates did not reflect actual usage and charges, urging them to rely on finalized billing data instead.
