PayPal has posted the following notice of a disruption in PayPal checkouts and IPN (Instant Payment Notifications) today.
Since we depend on IPN to receive order data along with confirmation of completed payments from PayPal, any delayed IPNs would have delayed our ability to process affected orders until PayPal caught up with their IPN backlog.
