This is taking ages to run, and it crashes before the end:
import cdsapi

dataset = “reanalysis-era5-single-levels”
request = {
“product_type”: [“reanalysis”],
“variable”: [“surface_solar_radiation_downwards”],
“year”: [“1974”, “1975”],
“month”: [
“01”, “02”, “03”,
“04”, “05”, “06”,
“07”, “08”, “09”,
“10”, “11”, “12”
],
“day”: [

],

“15:00”, “16:00”, “17:00”,
“18:00”, “19:00”, “20:00”,
“21:00”, “22:00”, “23:00”
],
“data_format”: “netcdf”,
“download_format”: “unarchived”
}

client = cdsapi.Client()
client.retrieve(dataset, request).download()

I guess it’s related to this, what is the pb ? Is some maintenance being done ?

Thank you !
