Until the AWS bill becomes finalized, AWS reserves the right to retroactively make updates on their billing data.
Example: Let's say the day of 9/27/2025 came and went, and an anomaly did not occur on this day. A policy could trigger today (10/1/2025) for an anomaly from four days ago (9/27/2025) if it is added to the bill retroactively.
Policies will not be reporting on anomalies older than 7 days.
