Active domains in Cloud Platform¶

In Cloud Platform, the first bare domain name you add to an environment is the active domain for that environment. This is true with, or without the www prefix. Environments containing no bare custom domains use the Acquia default domain as the active domain.

Cloud Platform uses the active domain for several purposes, including:

• Calculating the Acquia Insight score for an environment
• Monitoring uptime for your application

For more information about adding domain names to environments, see Adding a domain name.
