Wow this is the second time in just over a week I’ve stumbled across a big name dot com that is down for "maintenance". Having worked in this field for a while I’ve used “maintenance” pages like this on sites big and small as a more graceful application error page or during an upgrade or deployment.
I’ve always thought that when you’re a multibillion dollar retailer like Wallmart or a big name social networking site like LinkedIn it puts you in a different league where you have uber redundancy and 99.9% uptime. Seeing unexpected maintenance pages like this especially on Wallmart (a site that generates a lot of revenue from ecommerce) validates that my above mentioned approach is still used for websites of all shapes and sizes!
