I'm amazed at the responses saying something like, "It's great because when you go down, you can point to the BBC and say, it's not our fault, everyone is down." That should be the clue that this gives them enormous power. It's also bad for overall resilience. Better that businesses go offline more often in an uncorrelated manner, than go offline less frequently but simultaneously. I guess it's great if all you care about is not catching blame.
