2) Navigate to your destination

Other options

If there is no network issue on your side, please contact ECMWF via the Support portal. The Data Support Team will be able to assess whether a decline in the data rates has taken place. They also might be able to suggest an appropriate solution for your case, which could be for example increasing the number of parallel connections or the compression of your data (Bronze, Silver and Gold users only).
