@dicksonfu thanks for notifying us. We've switched from NOAA NOMADS to NOAA FTPPRD as our import source. FTPPRD seems to be faster in serving us data, which was slowing our import from NOMADS before. Latest update (reference time 2022-01-17T06:00:00Z) is already available as for now (2022-01-17T11:20:00Z)
