Re: Networking Pearl Harbor in the Making

Seems everyone considering the options would be well advised to
consider how availability/reliability is actually calculated and
based on that exercise make a more educated decision as to whether
this does yield improvements at a cost that can be absorbed.
Just because you have n different flavors doesn't mean availability
goes up. And you might find some surprises in how costs develop.
This isn't just about equipment, it's the operational impact as well.
Unfortunately, short of a verifiable economic cost being associated
with such a doomsday scenario, what a business case can carry is what
will be deployed. And regulation doesn't necessarily solve anything
here either (as it isn't cost neutral).
You can always build more availability. But can you afford to pay
for it. (IMHO, the DoD JSF effort is real world testament to what
happens when the cost of an ideal becomes so high that a compromise
must be reached to sustain the effort -- this very much has its
analogy in networking as well).
Or those are my $.02 anyway,
