How Will the New Sandbox Copy Architecture Improve Sandbox Routing?
|Knowledge Article Number||000214501|
With the new sandbox copy architecture deployed in the Summer '15 release, the copy engine selects the best instance for your sandbox based on available storage space, CPU consumption, and import activity on each sandbox instance.
It is important to keep in mind that since the copy engine uses all available resources to process sandboxes, it is likely your sandbox could change instances from one refresh to another. Be sure to follow best practices and avoid hard coded references to absolute URLs in code within your sandbox and login endpoints in integrations.
This feature will be made available on a rolling basis during the Summer ’15 release.
