Use a Unified URL for Your On-Demand Sandboxes
You can now access your on-demand sandboxes with a unified cluster-agnostic host name,
so you no longer have to remember the cluster that your sandbox belongs to. The hostname matches
the pattern <realm>-<instanceId>.dx.commercecloud.salesforce.com
, for example, zzzz-001.dx.commercecloud.salesforce.com
. It also matches the domain
name of the B2C centralized admin API server, admin.dx.commercecloud.salesforce.com
.
