Apple Website Goes Down

Apple's Apple Store online site is currently down when attempting to make a purchase of an Apple device or accessory, but it's not quite clear why the site is unavailable. 

Sometimes the Apple online store goes down due to an imminent product refresh, but at other times, the store becomes unavailable for routine maintenance purposes. 

We'll update this post with more info when the store comes back up. 

Update: The Apple Store website is back up and there doesn't appear to be anything immediately new, suggesting this was a maintenance update.
