Effective about 18 UTC July 21 the GPM MOC stopped sending data to the PPS. This was not a satellite or instrument issue. The problem appeared to be a network connection issue at the Emergency MOC which is currently receiving data as part of a monthly test of the backup facility.
Effective 21:41 UTC the data flow from the MOC to PPS resumed. Apparently there was a major network issue on that part of the network. It has now been fixed and MOC is sending data again.
