Update #1: The Impact and Expected End times for the planned PDA partial failover have been updated to begin May 26, 2020 at 1125Z and end May 27, 2020 at ~1425Z for a duration of 27 hours. These times include an earlier start time than originally planned and additional time for the completion of NDE processing at CBU after IDPS has switched back to NSOF.


Topic:  Planned PDA Partial Failover to CBU


Date/Time Issued:  May 22, 2020 2001


Product(s) or Data Impacted:  Due to planned and impactful IDPS network maintenance, all S-NPP, NOAA-20 and GCOM-W1 Level 1B (sensor data records - SDRs) and other ‘critical’ (data records - xDRs) designated products will be distributed from PDA at the Consolidated Backup (CBU) facility.  Delivery of GOES-16/17, Metop, POES and other data will continue nominally from NSOF PDA and other ESPC distribution systems.  


Date/Time of Initial Impact:   May 26, 2020 1130Z


Date/Time of Expected End: May 27, 2020 1130Z 

Length of Event:  24 hours


Details/Specifics of Change:   PDA pull users should initiate duel-flow, to pull all available products from PDA OPS and PDA CBU, during this event.  This change should be transparent to push users.  Pulls from CBU should continue until 2 hours after the end time listed above, as it takes NDE time to finish all product creation after receipt of the orbit. 


The PDA Support team will be monitoring the environment to quickly investigate and remediate anomalies that arise.
