Weekly Outage and Initial Catch Up
Every Tuesday morning (Pacific time) we begin a 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.

Final data is in the splitter queue.
As promised, we've stopped the process that puts new data into the queue today. Data distribution will continue until the files shown on the status pages are done. We'll be accepting results and resending results that didn't validate for a while.
