[Inaccurate Estimated Billing Data] Service impact: Inaccurate Estimated Billing Data

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 subsystem. The displayed billing estimates do not reflect actual usage and charges. There are no customer actions required at this time. Once the issue has been mitigated, we expect full resolution to take multiple hours as we work through recomputing the estimated billing data. We will provide another update by 6:00 AM PDT or sooner if more information becomes available.
