Service Disruption for Climate Data Store (CDS) Users - 08 September 2022 for 5-6 weeks
As of 23 March, the Climate Data Store (CDS) and Atmosphere Data Store (ADS) are the first two user-facing services operationally supported from our new Data Centre in Bologna. Following that successful migration, we would like to update you on the next steps in the transition to the Bologna Data Centre.
Following successful tests earlier this year (dry-runs of 5 April 2022, 26-28 April 2022 and 28 June-5 July), the ECMWF Data Handling System (DHS) Move, causing 28 days of reduced MARS (Meteorological Archival and Retrieval System) and ECFS (ECMWF's File Storage system (ECFS) service) services, is due to start on 08 September 2022.
This degradation of the service may impact some of our Climate Data Store (CDS) data users. This is because some of the data made available from the CDS are served from tapes in the ECMWF MARS system.
CDS data users should expect that some CDS datasets served from MARS tapes will not be accessible during the DHS move. Users may still submit CDS data requests which will remain in the queue until data access is resumed.
For more detailed information on the datasets affected, visit this ECMWF forum post: https://confluence.ecmwf.int/x/B9QvEQ We recommend our users to "Watch" this page announcement.
The information above is based on current expectations. For more details and to get notified about further updates and changes, please “Watch” ECMWF's dedicated confluence space.
Thank you for your patience during this significant migration to our new data centre which will enable exciting scientific developments and an overall better service to all ECMWF users.
