Yet, it is reasonable that people expect x % of their traffic to
use IX's. If those IX"s are gone then they will need to find another
path, and may need to upgrade alternate paths.
I guess the question is.
At what point does one build redundancy into the network.
I suspect its a balancing act between reducancy, survival (network)
and costs vs revenues.
not sure I'd call it a "poor job" for not planning all possible
failure modes, or for not having links in place for them.
