Weekly Outage and Initial Catch Up
Every Tuesday morning (Pacific time) we begin a ten hour data distribution outage for database and systems maintenance. The upload/download servers will be offline during this time. Afterwards you may experience connectivity issues for several more hours as the servers catch up with demand.
