The following has been resolved.
PayPal is currently upgrading some key site features which may result in delays in order placed today. We will update this thread when we have verified that orders are once again being completed immediately. For more information you can go to:
Live Site Status - PayPal Developer Community
Also you may e-mail firstname.lastname@example.org
if your order has been delayed for more than 24 hours and you will receive a free time card for your troubles, but we do not expect any orders to be delayed for that long.
