How to choose a transport(terrestrial/subsea)

[alfie at fdx.services (Alfie Pates)]

I'm of the opinion that, if you need resiliency, you should order
explicitly diverse circuits from a primary provider and then a secondary
circuit from a second vendor.
Ultimately, If you want contractually-enforced physical diversity then
the best options will be single-vendor solutions: Obviously you also
want to avoid an unknown single-vendor single-point-of-failure, hence
the secondary provider. Having two vendors is usually a less than
optimal solution since neither has visibility into the others' network
to ensure the physical diversity required for a truly resilient service:
what happens if an undersea cable is cut, etc?
The cost of such solutions is often unpleasant to justify, mind.
