It's also entirely possible that the behavior observed will change because of testing. The more a test looks different from "normal" residential traffic the more likely that it's going to be handled differently.

Hi Everyone,
Thanks for the replies! After reading them, i am doing some digging into DNS RFC's and haven't found much with respect to ANY queries. Not responding with full results to protect against being used in an attack makes sense. However, I find it odd that only 1 of the 4 anycast servers I tried would institute this.
it's possible (jason hinted at this) that the servers in question are not a homogeneous software set... and have different behaviour being displayed because of that.
Also, just because you sent a packet to 4 different ip addresses doesn't mean that they didn't end up on one or some of the same hosts behind loadbalancers/ecmp/etc, right? (so it's not clear you are/can test this properly from your vantage point)

(what's a bit concerning is my comcast link's not able to talk to cdns02 at all... over ipv4 at least, v6 works, thankfully I suppose)
