Yeah at first it was aggravating whenever I'd try and view posts not signed in. Then I read about the attacks happening and realized AOU is doing us all a favor by keeping the sight tight and ship-shape.

Makes sense and no surprises. I was curious more about the low level infrastructure because even if rate limited you can still be overwhelmed with DDOS at the swtich/router/host level. Which implies the need for RR distribution against multiple IPs. And you can't exactly have those openly exposed else they'll simply target those which in turn forces the pressure back up stream (switch/router/host(s)).

Everything on top of that is just gravy to help with the subversives. But thank you for the polite follow up.
