Date/Time of Expected End: May 6, 2026 1630Z

Length of Event: Estimated to be 52 hours

Details/Specifics:

On Monday May 4, 2026 a 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.

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 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.

PDA staff will be available to help troubleshoot users’ issues with failover and 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 is planned to be delivered via NCCF to both NSOF OPS and the CBU Backup sites.
