CAMS global atmospheric composition forecasts very slow

I am trying to download the cams global forecast data for the year 2025 using the API and it is very slow. One request took 12 hours (“request-id”: “25730c4d-8afc-4bc7-ac01-e567cf9b2239”)
I wonder if this is something expected or there is some issue. For the latter, when it is going to be fixed?
