Still not seeing additional latency from here:

(neodymium:15:44)% dig @2001:470:20::2 www.didi.nl. AAAA

And if that is already cached, let's try something that should require a
fresh lookup:

(neodymium:15:44)% dig @2001:470:20::2 tengigabitethernet.com. AAAA

; <<>> DiG 9.7.3 <<>> @2001:470:20::2 tengigabitethernet.com. AAAA

;; ANSWER SECTION:
tengigabitethernet.com. 3600    IN      AAAA    2001:48c8:1:104::e

;; Query time: 84 msec

Again, not too bad..
