Browser Hangs when Accessing the Arduino Reference

it seems when click on / reference chrome browser hangs long time.

chrome gets following errors:

redirect @ origin 'http://arduino.cc' has been blocked loading cross-origin resource sharing policy: no 'access-control-allow-origin' header present on requested resource. origin 'null' therefore not allowed access.
