Service impact: Inaccurate Estimated Billing Data - AWS Outage

Summary

We continue to work to resolve the issue affecting estimated cost and usage data displayed in the Billing and Cost Management Console. We are actively working on multiple mitigation paths in parallel. The first path involves reverting to the last known good estimated bill computation. With this approach, customers will only see cost and usage data through July 15, however the inflated cost data will be removed. The second path involves rolling back a recent change to the billing computation subs
