AWS billing bug showed customers fake bills of billions
Original: Amazon fixing bug that billed some AWS customers billions of dollars
Why This Matters
A billing system failure at AWS — the world's largest cloud provider — highlights the operational risks of cloud infrastructure at scale.
Amazon confirmed on July 17, 2026, that a bug in the AWS billing portal displayed wildly inaccurate charges to some customers — including estimates as high as $2.5 billion — due to a faulty change in its billing computation subsystem. Amazon stated the figures do not reflect actual usage.
On July 17, 2026, some Amazon Web Services customers discovered shocking billing estimates in the AWS portal, with one customer shown a charge of nearly $2.5 billion for a single month's usage. Others saw estimates ranging from several million to hundreds of millions of dollars — all for services they had not actually used. Amazon confirmed the issue stemmed from a bug in its billing computation subsystem, with inaccurate data first appearing late Thursday. The company attempted a rollback of a recent change but acknowledged on Friday morning that the rollback 'did not resolve the issue.' Amazon's status page indicated the problem was expected to persist for several more hours. In a statement, Amazon said the estimates 'do not reflect actual usage and charges,' suggesting affected customers will not be held responsible for the erroneous figures. Screenshots shared by AWS customers on Reddit illustrated the scale of the erroneous bills. Amazon spokesperson Aisha Johnson referred TechCrunch to the status page and declined to answer whether any AWS accounts had been suspended as a result of the billing error.
