SLA changes
- May 25, 2022Amazon EC2Amazon Compute SLA narrowed to EC2 only; the May 5, 2022 version listed EC2, EBS, ECS and Fargate as Included Services under one SLA. Percentages unchanged (99.99% region, 99.5% instance).Source
- May 5, 2022Amazon EC2Instance-Level SLA of 99.5% monthly with 10/30/100% credits introduced, replacing the July 22, 2020 'Hourly Commitment' (Single EC2 Instance Hourly Uptime Percentage of at least 90% per clock hour, otherwise that instance hour is not charged).Source
- Mar 20, 2019Amazon S3 (Standard)S3 Standard credit schedule gained a 100% tier below 95.0% (and a 25% band 95.0-99.0%). April 4, 2018 version: 99.0-99.9% = 10%, less than 99.0% = 25%. March 20, 2019 version: 10% / 25% / 100%. Standard-IA got the same 100% tier below 95%. The 99.9% threshold did not change.Source
- Mar 19, 2019Amazon EC2Third credit tier added: below 95.0% now earns a 100% credit (February 12, 2018 version topped out at 30% for 'Less than 99.0%').Source

About AWS
All SLA pages fetched 2026-09-23. AWS support was restructured: per the AWS Support FAQ, Developer and Business Support closed to new subscriptions on December 2, 2025 and will be discontinued January 1, 2027; Enterprise On-Ramp is supported through December 31, 2026. The current plans page lists only Business Support+, Enterprise Support and Unified Operations, so full response tables for the legacy Developer, Business and Enterprise On-Ramp plans are no longer published; only the critical-issue times quoted in the FAQ are recorded. The S3 change is verified from Wayback snapshots (20181206174531 showing the April 4, 2018 version and 20191002235233 showing the March 20, 2019 version); EC2 changes come from AWS's own historical SLA page.

Highest commitment: Amazon DynamoDB, 99.999% (Global Tables SLA).
