SubmitMultiRegionAccessPointRoutes - Amazon Simple Storage Service

SubmitMultiRegionAccessPointRoutes

Note

This operation is not supported by directory buckets.

Submits an updated route configuration for a Multi-Region Access Point. This API operation updates the routing status for the specified Regions from active to passive, or from passive to active. A value of 0 indicates a passive status, which means that traffic won't be routed to the specified Region. A value of 100 indicates an active status, which means that traffic will be routed to the specified Region. At least one Region must be active at all times.

When the routing configuration is changed, any in-progress operations (uploads, copies, deletes, and so on) to formerly active Regions will continue to run to their final completion state (success or failure). The routing configurations of any Regions that arenât specified remain unchanged.

Note

Updated routing configurations might not be immediately applied. It can take up to 2 minutes for your changes to take effect.

To submit routing control changes and failover requests, use the Amazon S3 failover control infrastructure endpoints in these five AWS Regions:

us-east-1
us-west-2
ap-southeast-2
ap-northeast-1
eu-west-1

Important

You must URL encode any signed header values that contain spaces. For example, if your header value is my file.txt, containing two spaces after my, you must URL encode this value to my%20%20file.txt.

Examples Sample request for initiating failover

In the following example, the request to submit these routing changes to initiate a failover is sent to the failover control infrastructure in the us-east-1 Region. In this example, the eu-north-1 Region is set to active, and the ap-northeast-3 Region is set to passive. In other words, the ap-northeast-3 Region is failed over to the eu-north-1 Region.
