Internet Data Center :
Build vs Buy Decision
Content Support Model
Carrier-neutral IDCs get many carriers offering services at this ring (i.e. Equinix, S&D)
ISP-neutral IDCs get many ISPs at this ring (i.e. Equinix, S&D)
IDCs without managed services groups may have many providers competing at this ring
Raw Colo space providers offer basic space and power at this ring (i.e. DRT)
All things considered equal, content companies should prefer data centers for which there is multiple levels of redundancy in infrastructure as well as a diversity of paths to get out at layer 1, layer 2, and layer 3.
