**UPDATE on 28-Feb-2024** : **[Please read: CDS and ADS migrating to new infrastructure: Common Data Store (CDS) Engine](https://confluence.ecmwf.int/x/uINmFw)**

* * *

We are pleased to announce that the Atmosphere Data Store (ADS) is being modernised **&nbsp;** to better manage the growing workload, computing demand and better serve its current and future users. This modernisation affects all layers of the infrastructure: the front-end web interface, the back-end software engine and the underlying cloud. infrastructure hosting the service and core data repositories. **The new modernised ADS is expected to be launched in Spring 2024.**

While the modernisation process has so far been transparent to users, it has now reached the stage when data is being migrated onto the new infrastructure and this, unfortunately, is impacting services. **This migration period will take several weeks to complete, during which users should be expecting some unavoidable disruption and degradation of service** on the ADS such as:

- longer queues
- requests being canceled
- temporary closure of queues
- requests failing with unusual error messages
- catalogue temporarily offline

Relevant information (e.g. activation of new single sign-on ECMWF account) will be shared with ADS users nearer the time of the launch.

We understand the inconvenience the disruptions are causing during this time. The Data Store team is working hard at keeping disruption to a minimum.&nbsp;

We will keep our users informed with the latest details on this announcement page. We therefore recommend users to **"Watch" this page** to receive email notifications of updates on this announcement.

We thank our users for their patience during this significant modernization of the ADS which will enable exciting scientific developments and an overall better service to all ECMWF users.
