There is definitely a benefit to the customer once the data is stored on
the cache.  However, in order to scale at a reasonable cost one would
probably want to build a hierarchy in the caching servers.

With or without a hierarchy of caches (such as local area and network
border caches); the first user to request data through the cache will be
penalized with an additional delay not present in direct access.
