On Tuesday, 20 January 2026,  NASA's Precipitation Processing System (PPS) will temporarily shutdown the GPM Near Real-time (NRT) system at 18:00 EST (23:00 UTC).  This is necessary to complete the move of data from the current high-speed storage system (not currently under maintenance) to the new storage system that is under maintenance.  It will take approximately 14 hours to finalize the synchronization of the data from the old storage to the new one.

During this 14 hours no new data will be produced or ingested. While user access to the file server (jsimpson.pps.eosdis.nasa.gov and jsimpsonhttps.pps.eosdis.nasa.gov) will be possible, no new files will be available.

After this period, the entire system including the segment that processes spacecraft raw data as well as the file server will need to undergo a final synchronization. The PPS estimates it will take 2 hours to complete this step. The step is anticipated to occur between 08:00 and 10:00 EST (13:00-15:00 UTC).  Again no access will be available during this period.

The PPS anticipates the GPM NRT server should be accessible again on 21 January 2026 by 12:00 EST (17:00 UTC).
