The random nameservers are only accidentally a defense against this attack. They're avoiding SPOFs, including TLDs -- you never receive nameservers in the same TLD for example. It's a reliability and scaling consideration with this accidental benefit. Most admins don't think about a complete TLD failure. Amazon did. |

>> Most admins don't think about a complete TLD failure. Amazon did.
I think companies such as Google or Facebook did think that before, but I am not sure why they didn't follow this trick.
