Service access endpoints#

The Cloud Servers API is a regionalized service. The user of the service is therefore responsible for selecting the appropriate regional endpoint to ensure access to servers, networks, or other Cloud services.


To help you decide which regionalized endpoint to use, read about special considerations for choosing a data center.

If you are working with cloud servers that are in one of the Rackspace data centers, using the ServiceNet endpoint in the same data center has no network costs and provides a faster connection. ServiceNet is the data center internet network. In your authentication response service catalog, it is listed as InternalURL.

If you are working with servers that are not in one of the Rackspace data centers, you must use a public endpoint to connect. In your authentication response, public endpoints are listed as publicURL. If you are working with servers in multiple data centers or have a mixed environment where you have servers in your data centers and in Rackspace data centers, use a public endpoint because it is accessible from all the servers in the different environments.


If you do not know your account ID or which data center you are working in, you can find that information in your Cloud Control Panel.

The following table lists the Cloud Servers endpoints that are available for each region.

Regionalized service endpoints#



Chicago (ORD)$TENANT_ID/

Dallas/Ft. Worth (DFW)$TENANT_ID/

Northern Virginia (IAD)$TENANT_ID/



Hong Kong (HKG)$TENANT_ID/

Replace the $TENANT_ID with your actual account number that is returned as part of the authentication response. The account number is located after the final slash (/) in the publicURL field.


You should copy the base URLs directly from the catalog rather than trying to construct them manually. You can find the complete URI to access the Cloud Servers API that includes your account number in the service catalog returned in the authentication response. Search the catalog for the service name, cloudServersOpenStack. Then copy the URI from the publicURL field included in the service information.

The Identity service returns a service catalog, which includes regional endpoints with your account ID. Your account ID, also known as project ID or tenant ID, refers to your Rackspace account number.
