Also when troubleshooting HTTP connectivity in general but can be really help when dealing with a transition from IPv4 to IPv6 if you install the browser extension IPvFoo for Chrome (IPvFox for Firefox) it can take out a significantly complicated step in the troubleshooting process as it easily shows you all of the IP addresses (v4 and v6) being connected to on any given page and which are SSL and or non-SSL as well. It's very small and quite useful.

That is just pure DNS selection luck...

Note that a lot of properties on this massive Internet are using
Geo-DNS, load-balancing, BGP-based routing tricks/anycasting and a lot
of other nasty funny tricks.

Hence, as you did not include any traceroute or other data, little else
anybody can say...
