You can access inactive releases via SSH to preform maintenance or debugging:

  • ssh deploy@adminssh.<release_id>.<environment>.<fleet name>.f.nchr.io

You can also access inactive releases via the web:

  • http://admin.<release_id>.<environment>.<fleet name>.f.nchr.io
  • http://www.<release_id>.<environment>.<fleet name>.f.nchr.io

Note that you will need to disable Magento's automatic base-URL redirects to access these URLS.
