Rather than saying the colo itself is a single NE, maybe this could be
changed to say the colo is a facility that *houses* one or more NEs.
I don't know whether colo physical security is in scope, but volumes could
be written on that if so.
Agree on your point re ownership (customer vs. NSP). However, I'd argue
that even in a NSP-only context, a customer-owned box in a colo is
in-scope since vulnerabilities in its default security settings may allow
compromise of other systems, including the NSPs.
