On Monday evening, September 19th, we will perform routine system updates commencing at 9:00 PM, PT. During this event, Newton will be unavailable for a short time. We expect to restore full connectivity within two hours, by 11:00PM, PT. If you happen to be using Newton when we begin making updates, you may receive a "lost connection" message. You can reestablish your connection by logging in again after the maintenance window. If you experience other issues please email support@newtonsoftware.com.
