Website bug, 404 errors with content
Seems part of the Apple website have broken content (some are images others are videos)
On AirPort Base Station Firmware Update 7.7.3, the main image is missing and on http://store.apple.com/us/product/HFQQ2ZM/A/adidas-micoach-smart-ball the video is missing, there might be other parts with missing content aka 404 errors
I am seeing in this on OS X 10.9.4 (saw it on 10.9.3, pointing to a website bug)
