Apple Store Down in advanced of iPad 2 event

Wow, still 3 hours to go before the iPad 2 event and the Apple Online Store is already down? The chances of iPad 2 being available to buy following the event are slim but could pre-orders start as soon as today? Could something else be getting an update? (No white iPhone 4 rumors, please!) Or is this just the worst scheduled maintenance window ever?
