Please be aware that several planned maintenance sessions on our Cloud infrastructure this week (28-30 April 2025) may affect the normal operation of the Data Stores, e.g. with potential impact on request queues, running of applications, API downloads, websites etc.
Should users encounter difficulties, we recommend in the first instance to please check the ECMWF Service Status page for the latest information available with respect to ongoing system sessions.
Please refrain from submitting requests as long as “Data Stores” is not showing in green (all clear) status on the ECMWF Status page.
We thank our users for their patience.
