AWS Post-Event Summaries
The AWS Health Dashboard provides the latest health information for AWS services across the globe, as well as the Service History for the preceding 12 months. When an issue has broad and significant customer impact that results in the failure of a significant percentage of control plane API calls, impacts a significant percentage of a service’s infrastructure, resources or APIs or is the result of total power failure or significant network failure, AWS is committed to providing a public Post-Event Summary (PES) following the closure of the issue. Post-Event Summaries will remain available for a minimum of 5 years and will provide the issue’s scope of impact, factors that contributed to the issue and the actions taken to address the risks identified.
