Undersea fiber cut after Taiwan earthquake - PCCW / Singtel / KT e tc connectivity disrupted

Hi Sean, 

I don't really understand your argument. I have no clue what this 'assurance' means in the context of managing telecommunications networks. 

No one is claiming that risk can be eliminated - but can be greatly reduced by proper physical diversity. 

And for the Federal Reserve, I don't necessarily believe they are experts in building telecommunication networks. They may be, but you have do more than just assert it. 

For all I know, the groups you cited are simply not that good at managing network risk. 

Maybe there is a compelling argument, but you have elaborate it.

Uhm, did you bother to read the NDAI report?  The Federal Reserve learned
several lessons.  Fiber maps are not sufficient.  If you are relying 
just on fiber maps, you are going to learn the same lesson again and 
again.

The FAA, Federal Reserve, SFTI and SMART are probably at the top as
far as trying to engineer their networks and maintain diversity 
assurances.  But even the Federal Reserve found the cost more than
it could afford. What commercial banks are doing is impressive,
but only in a "commercially reasonable" way. Some residual risk and 
outages are always going to exist.

No matter what the salesman tells you, Murphy still lives.
