As of today we've become aware of some issues we're having with our CDN provider that are being worked on.
If you can't load the site please go to the following link: http://www.ipdiagnostics.com/request.action?client=akamai&case=F-CS-1502182&URL=www.wowhead.com -- it may help the provider further troubleshoot. -- This avenue is no longer available.
Thank you.
Edit: Still working on this... if you can't load the site, try loading http://www.wowhead.com/jsdebug and send the text contained within (if you get any errors) to feedback@wowhead.com so I can forward it to a dev team member. Thank you.
