As usual Apple have taken measures and taken down their Apple store in the run up to the 10am conference which is taking place in San Jose, up there instead is a placeholder which I have managed to screenshot below for you. The placeholder is an animated message that states that the Apple Store will be back, this message has been translated into a number of different languages that the animation scrolls through.

The message says that Apple are currently updating the store for you, and business will resume soon.
