Several AWS customers report receiving unexpected billing estimates showing dramatically inflated amounts, ranging from a few cents to figures in the billions. Multiple outlets say the issue appears in billing estimates displayed to customers, including billing-console or related estimate communications that use a computation subsystem. Amazon attributes the problem to a unit-pricing error in the AWS Billing Console’s estimated billing calculation. In some cases, customers who had paid small amounts or incurred minimal charges reportedly saw estimated totals that were orders of magnitude higher than their actual usage would suggest. Amazon says the displayed billing estimates do not reflect actual usage and charges. The reports describe the erroneous estimates as appearing after customers logged in on Friday, prompting concern among users when the estimates suggested extremely large fees. The Next Web cites Amazon’s confirmation and notes examples where very small prior charges corresponded to vastly larger estimated totals, including one estimate reported as reaching $2.5 trillion. Across coverage, the common theme is that the bug affects estimated billing outputs rather than the underlying billing for actual service usage.
