Clients should be prepared to handle HTTP 301 Moved Permanently responses, as we may leverage this mechanism to effect URI migrations, especially between major API versions.

A sample request might be the following:

GET /v1/infrastructure-regions HTTP/1.1
Host: seiso.example.com

A sample response might be:

HTTP/1.1 301 Moved Permanently
Location: https://seiso.example.com/v1/regions

To simplify client-side implementation, we recommend implementing redirect-handling code in a cross-cutting fashion so you don't have to implement it for every request.

See the Wikipedia article on HTTP 301 for more information.
