there was some odd outages in recent weeks and i'm betting that they have just slapped CF on their whole infra to stop some attack on it
that's not how you do it lol... also, you don't do shit like this and not tell your support crew about it so they can pacify the customers because i'm so gone at this point, it's only the host that can do shit like this, i'm sure of it, i don't think there is a way to do it from DNS side
it's a router thing, DNS does not connect to routing
