This is work in progress. More information will be added as soon as it becomes available. |
The purpose of this space is to keep users of ECMWF services informed about the move to the new data centre, update them any service disruptions or degradation this might cause and to highlight any action user might need to take.

Action to take
DHS move (MARS and ECFS)
The Data Handling System (DHS), providing the MARS and ECFS services, needs to be moved to Bologna before the new Atos HPCF will produce an increased archive load. The migration is shown in the transition plan where all events are relative to day D, when the access to MARS and ECFS in Reading will move from ..be switched off. The DHS move is expected to last up to 4 weeks. To minimise the impact of the move, essential data, necessary to continue operational and time-critical activities, has been identified and archived in a Temporary-DHS. Before the DHS move we will conduct a number of dry-runs, during which the access to the main DHS in Reading will be blocked, to verify that the Temporary-DHS contains all essential data necessary to continue all critical activities. Some of the dry-runs will last for 1-2 days. A final longer dry-run, lasting 5-7 days, is expected to happen 4 weeks before the move and will help to establish the exact date of day D.
Main service disruptions
Date | Duration | Impact | |
---|---|---|---|
Dry-run 1 | TBA | TBA | TBA |
Dry-run 2 | TBA | TBA | TBA |
... | ... | ||
Final dry-run | October 2021, TBC | 5-7 days | degraded access to non-essential and non-valid data |
DHS-Move | November 2021, TBC | 28 days | degraded access to non-essential and non-valid data |
Impact to MARS service
No impact
The following services/data are not expected to be impacted by the dry-runs and the DHS-move
- Operational Forecast Production (EMOS, ERA5T, CAMS, …)
- Access to recent operational data (verification time less than 1 month in the past)
- Archiving/storing into MARS
- MS Time-critical suites
- Atos HPC Alpha/Beta testing
For any other services/data please see below.
Access disabled
The following services/data will not be available during dry-runs and the DHS-move
- WebAPI public
- ADS/CDS external
- TIGGE/S2S/RD
- Historical data: OD, ERA5
Degraded service/data access
The following services/access to data will be degraded during dry-runs and the DHS-move
- WebAPI registered (private)
- MARS
- ERA5 BX production
Impact to ECFS service
During services disruptions retrieval of any data which has not been identified as essential will be degraded or not be possible. Archiving into ECFS should not be affected.
