Purpose of Google AMP Cache
The Google AMP Cache serves cached copies of valid AMP content published to the web. Serve content directly from the Google AMP Cache to provide a fast user experience.
The Google AMP Cache automatically requests the latest version of the AMP document from its origin and serves the updated version to the next user. That means that when you load the AMP Cache URL directly, that forces the cache to update, even without the more “urgent” update ping method.
