Are the zones monitored by independent NOCs, and operated by completely diverse NOC
engineers so the same finger-fumble or automated provisioning tool can't be applied to
configs in both locations?

I've seen someone press 'commit' to a router config script with a typo  that proceeded
to take down approx. 45 routers across 20-something countries. Each country was
completely independent at the infrastructure level then, too.

+1 What Mark said above. If your multiple diverse services stem ultimately from the
same boardroom table, you aren't diverse.
