A "site" gets assigned a /48. It could be a customer site, or one of
your many sites
or one of a customer's many sites. I interpret "site" to roughly be
within a single
building, although a campus type arrangement could be considered a single
site if the network architects want to do it that way.

It's purely a case of stage 2 which is a good thing IMHO, since it
shows some movement forwards past denial.
