I heard that it initially had AAAA records. After the site couldn't keep up with the initial load, it was migrated to Akamai's CDN (the DNS records you see now are those), and Akamai doesn't yet offer IPv6 in production, so no IPv6.
there are places in this world with working v6 at scale.... the folk involved COULD use them. (I thought, actually, that akamai's v6 offering was actually production, just not wide-spread?)
Not sure - our Akamai support people have so far not told us that it's production ready (we ask periodically; maybe we aren't talking to the right people). And thus far, they haven't permitted us to point the www.upenn.edu AAAA record to Akamai. A non production name (ipv6.upenn.edu) mirroring the same content does have a AAAA to Akamai though. But, checking www.worldipv6launch.org just now shows that it have IPv6 records now: ;; QUESTION SECTION: ;www.worldipv6launch.org.
