Many non colo buildings, old, or otherwise, don't have two 0 manholes,
don't have the riser infrastructure, etc. etc.
If you aren't already a carrier, you could end up spending a whole
of money on conduit leases, facilities leases, and commitments to
carriers that have to dig out from a diverse manhole, fees to the landlord
for boring the foundation and building the entrance facilities..etc.
Landlords today are very smartly getting involved in owning the core
infrastructure <splice boxes, cross connects, conduit> and leasing
it back to business, net, and carrier companies.
