AWS 主動提高 Amazon EC2 與 Amazon EBS 的 SLA：「Announcing an increased monthly service commitment for Amazon EC2」。
Amazon EC2 is announcing an increase to the monthly service commitment in the EC2 Service Level Agreement (“SLA”), for both EC2 and EBS, to 99.99%. This increased commitment is the result of continuous investment in our infrastructure and quality of service. This change is effective immediately in all regions, and is available to all EC2 customers.
之前是 99.95% monthly (參考前幾天的頁面：「Amazon EC2 SLA」)，現在拉到 99.99% 了。第一階的賠償條件也從 99.95%～99% 改成 99.99%～99% 了 (賠 10%)。
