AWS Billing Outage: Incorrect Cost Estimation Data
AWS 經歷了一次廣泛的問題，導致 Billing and Cost Management Console 顯示不正確的預估帳單數據。根本原因已確定為預估帳單計算子系統中的單價問題，這觸發了數千名用戶的錯誤預算警報。
Root Cause and Resolution
AWS 確認該問題始於 2024 年 7 月 16 日 PDT 下午 7:38。工程團隊將根本原因確定為預估帳單計算子系統中的單價邏輯故障。
根據官方 AWS Health Dashboard，狀態更新提供了以下時間線：
- July 16, 7:38 PM PDT: Incorrect estimated billing data began appearing in the Billing and Cost Management Console.
- July 17, 3:03 AM PDT: AWS identified the root cause as a unit pricing issue in the estimated billing computation subsystem and began working on a mitigation strategy.
- July 17, 4:00 AM PDT: AWS expected full resolution to take several hours as they recomputed the estimated billing data.
AWS 明確表示，這些顯示的預估值並不反映實際使用量或費用，且用戶無需採取任何行動。
User Impact and Experience
用戶報告收到與其使用模式完全不符的預算警報金額。報告的數字範圍從數百萬美元到數兆美元不等，部分用戶報告的預估值甚至超過了 190 兆美元。
