Subscriptions processed later than normally today. They are currently running (11:08am US Pacific Time), and should all be processed within the hour.
We have identified the cause (a subscription with invalid data), but have not yet determined how the data came to be corrupted.
We will be improving our subscription processor immediately to prevent an error like this from causing widespread problems like this in the future. We will also be working to determine how this subscription became corrupt in the first place.
We apologize for the inconvenience, and are working hard to ensure this doesn't happen again.
