Topic:  2025 Planned PDA Limited One Day Partial Failover to CBU COOP Exercise

Date/Time Issued: June 13, 2025 1818Z

Product(s) or Data Impacted:  All products distributed from PDA. Some products will be available at CBU and some will be unavailable for part of the maintenance window.  

Date/Time of Initial Impact: June 25, 2025 1200Z

Date/Time of Expected End: June 25, 2025 2200Z

Length of Event:  Estimated to be 10 Hours

Details/Specifics of Change:

On Wednesday June 25, 2025 a single day Continuity of Operations (COOP) activity will take place initiating a failover of PDA operations to the Consolidated Backup (CBU) site in Fairmont WV. The transition to the CBU site is expected to take between 1 to 2 hours. When the CBU PDA system is active,  products from the NCCF environment will be available there. This will be a partial activation of the Consolidated Backup (CBU) site at Fairmont, WV. The failover is expected to begin with the first orbit received after 1200Z on June 25 and end with the next orbit received after 1800Z on June 25. The exact day and time of the failover will be announced closer to the event. It is noted that the S-NPP, NOAA-20 and GCOM-W1 data and products will have transitioned to NCCF and be available from either or both sites. For data that is both available at from the primary AND backup sites, users that PDA PUSHES to will receive data from both sites (DUPLICATES). When the COOP testing has completed, the configuration will be returned to the nominal PDA OPS system at NSOF. GOES-R and Legacy data will be available at the NSOF. Files from NCCF, and some passthrough data may be available at both the NSOF and CBU sites. To maximize available data, we encourage users to pull data from both sites during the COOP exercise. Pull users will be safe to retrieve data from both sites starting at the time of partial failover and through the completion of the failback activity. The failback activity from the CBU site to the NSOF site is expected to take approximately 2 hours. This is a high-level announcement for awareness of general dates and details. In the near future follow-on notifications will provide additional detailed, product specific information regarding availability. PDA staff will be available to help troubleshoot users’ issues with failover from 1330 UTC until 1700 UTC on Wed June 10. PDA staff will also be available Wed June 10 from 2000 UTC until 2200 UTC for assisting with users’ failback issues. Email PDA_DHS@noaa.gov and a PDA Support team member will provide the Google Meet details or phone number.  A declaration of Critical Weather (CWD) before or during this event may change, postpone or cancel the date of the COOP. JPSS data will be available from either site as it planned be delivered via NCCF to both NSOF OPS and the CBU Backup sites.
