 Every Dev Portal instance has an auto-generated default URL. You can also manage custom URLs within {{site.konnect_short_name}}.
 This gives users the ability to access the Dev Portal from either the default URL, for example `https://example.{geo}.kongportals.com`, or a custom URL like `portal.example.com`.
