Contact at "ec.europa.eu" / IPv6 broken

[Phil Mayers]

Can others confirm that this site:

http://ec.europa.eu/

...is broken over IPv6, but working over IPv4? Seems like the webserver 
is returning a 503 over IPv6 only.

We reported this last week, but have received no reply; does anyone have 
contacts into the hosting organisation that can bump the issue? We tried 
contacting the site via voice, and were politely rebuffed.
