Same here, though with a caching Debian package proxy instead of an
actual mirror. Nonetheless, s.d.o only sees one download of a given
security update even though it's actually being retrieved by
hundreds of machines.

For that matter, we also have a separate network for facility
security systems which is not connected to the Internet, and once a
month we rsync a detachable drive on an Internet-connected machine,
then sneaker-net it back to the system acting as a security update
repository for the other hosts.
