To make matters worse, exchanges of routing information are not particularly secure right now, and hackers are beginng to attack the routing infrastructure. Responses to these reliability problems are aggravating the situation. This increases the complexity of overall internet routing, and also means that they have to set up much more complex route advertisements, which are more prone to error. Reliability issues will increasingly hit the front pages of the newspapers. It is worth noting that virtually all the disruptions in the past year have been accidental.
Capacity is another big issue.
It's profoundly troubling because we have spent almost a decade trying to persuade people that they should assume that the network will have sufficient capaicity to permit them high-quality access to remote resources and now the capacity isn't there. Network performance is bad enough that some institutions are calling the idea of using the public internet for access to critical information resources into question. They feel that they now need to think about supplementing the public internet with private networking links or moving the critical resources inhouse. It will be a great tragedy if we must retreat back to that sort of world. The biggest capacity problems on the network seem as if they are nobody's problem to solve.
