It works for me, too.

Can you replicate this issue on other machines and vantage points?

Loads for me (from AS5539).  

Most of the content is loaded over IPv4, though, except some bits that 
come from l.yimg.com - those are successfully fetched via IPv6.

http://l.yimg.com/ also works ("Your requested URL was not found", but
that is quick and over IPv6).

Basic HE fails on this - it only handles "ensure that the connect succeeds,
without long timeouts if one of the protocols would time out".  Dunno about
the specific implementations in browsers.
