When I said "flip the switch" I of course meant who configured the system that automatically makes the change around midnight. I wasn't suggesting that someone actually moved a mechanical switch.
As for finding someone in-the-know from both networks, I'll be staying tuned to read about it if and when that happens.
In the meantime, it's the vagaries of the Internet to me. I'm still hard pressed to understand how any ISP an individual uses can be responsible for that individual's packets regardless of what corner of the globe the packets are traveling to and from.
