/** IPv6 AAAA connectivity testing *******************************************************
*
* Description: Uses hidden images to measure the possible negative impact of IPv6
* enabling the Wikimedia sites.
* This works by adding a hidden div to the footer with several image tags.
* The source addresses of the image tags are set to domainnames which have v4, v6 and
* both address types set. The script times how long objects take to load.
* Results are sent back to the server. http://ipv6and4.labs.wikimedia.org/stats.html
* Based on http://www.braintrust.co.nz/ipv6wwwtest/
* Contact: [[User:Gmaxwell]], [[User:Mark Bergsma]], [[User:Mindspillage]]
