Don’t they have their own DNS? It’s called Route 53 I think?
Though I don’t think you are required to use it with your AWS hosts. But that’s not exactly what I meant by pulling the plug. They could quite literally pull the plug on your service. (Disconnect you from switches/routers, power off your hosts, etc.)
Why only block them in the US, allowing people outside the US or on VPNs to confirm search results exist for those terms? Why not just block them everywhere?
But it hasn’t always been that way.
