This section provides information Pantheon platform domains.
Pantheon issues platform domains for all environments. Each environment (Dev, Test, Live, and each Multidev) is accessible via the platform domain, and matches the following patterns:
All platform domains are available over HTTPS. Redirecting to HTTPS during development and testing is a recommended best practice to ensure you are ready to go live with HTTPS. Refer to Redirect to HTTPS for more information.
Pantheon serves a default
robots.txt that disallows crawlers on platform domains, such as:
Crawlers are allowed on the Live environment for requests served with a custom domain (for example,
www.example.com). The default
robots.txt will be served if you attempt to access your Live environment with a platform domain, even if you have a domain associated with the environment.
Pantheon does not allow crawlers on Dev, Test, or Multidev environments. Adding a custom domain to an environment other than Live will not permit crawlers to that environment.
