AWS Billing Glitch Shows Customers Billions in Estimated Charges

A bug in Amazon Web Services' billing system caused some customers to see estimated charges in the billions or even trillions of dollars, though the company confirmed that actual invoices were unaffected. The glitch, which began on July 16, stemmed from a faulty configuration change that led to incorrect unit pricing in the billing computation subsystem. Source: Gizmodo Source: TechCrunch
