I'm getting doubts that you even know what the Internet is and how it works. If that's the case, I'm out. Seriously, you seem to know what an EMP is yet you fail to grasp that the Internet in its concept is not vulnerable to the EMPs at all. The power grid is vulnerable because the energy business is the only business that is not regulated. Typically regulation would require basic defence of the critical infrastructure against natural disasters but it's not the case with the power stations (at least not in the US). If the connections between nodes were properly shielded there would be no threat to the Internet from even a nuclear explosion.
