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.
