This site compares the RAPv4 run at EMC to the operational RAPv3. Information on RAPv4 developed by ESRL/GSD can be found at this link. The 'status' button shows a plot displaying the wall time of the last 72 hours of RAPv4 analyses and forecasts and the reasons for any failures. The 03, 09, 15, and 21Z cycles run out 39 hours. All others run out 21.
