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:
dev-site-name.pantheonsite.iotest-site-name.pantheonsite.iolive-site-name.pantheonsite.iomultidev-env-site-name.pantheonsite.io
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.
Platform domains are provisioned automatically and are non-configurable. Attempting to add variants of a platform domain (e.g. foo.site-name.pantheonsite.io) as a custom domain will result in an error.
robots.txt
Pantheon serves a default robots.txt that disallows crawlers on platform domains, such as:
/*.pantheonsite.io/*.pantheon.io/*.gotpantheon.com/*.sites.my-agency.com
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.
