Special Service Guide Update for June 27, 2019
The Amazon S3 Canary logging endpoint will be deprecated on October 31, 2019. The S3 Canary logging endpoint is no longer available to new customers. It will not be supported beyond the deprecation date for existing customers. Our existing Amazon S3 logging endpoint, with its associated API, offers the same functionality as the deprecated logging endpoint, making the canary version unnecessary. Current users should migrate their logging endpoint to Amazon S3.
