Big Tech Amazon A bug in AWS has caused some customers' bills to spike from a few cents to billions of dollars “The displayed billing estimates do not reflect actual usage and charges,” Amazon said. By Will Shanklin July 17, 2026 1:07 pm EST u/killpowa / Reddit If you've ever gotten an unexpectedly high bill, you know the panic that can quickly set in. Well, imagine that, only for a sum of over a billion dollars. That's what happened to some Amazon Web Services (AWS) users beginning Thursday evening. Fortunately, it was only a bug, and Amazon is working to fix it. Forums and social media were full of posts from uneasy AWS customers detailing their sky-high bills, many in the millions or billions of dollars.
One Reddit user even claimed their usage was being billed at $4.2 trillion. An AWS spokesperson wrote that "the displayed billing estimates do not reflect actual usage and charges." The AWS Service Health Dashboard states that the problem stemmed from incorrect unit pricing in its estimated billing computation system. At the time of publication, Amazon was still working on a fix. In the meantime, the company has paused estimated billing updates and is reverting its system to the most recent accurate billing data.
