Dear all,

We would like to inform you about an upcoming scheduled maintenance window on the EUMETSAT side of the European Weather Cloud. The maintenance will take place from 22 June 2026, 06:00 UTC to 26 June 2026, 14:00 UTC.

This intervention is required to perform a major upgrade of the underlying Ceph storage system. No service interruption is expected, and all existing virtual machines and services should continue to operate normally throughout the maintenance.

While we do not anticipate user‑visible impact, there may be occasional periods of reduced performance or slower operations due to temporary load on the storage nodes during the upgrade. We recommend keeping an eye on workflows that are particularly sensitive to I/O performance.

We appreciate your understanding and cooperation. Our team and the cloud provider will be closely monitoring the environment during the entire maintenance window.

For updates during the maintenance, please refer to the Service status | The European Weather Cloud.

Best regards,

EWC Team at EUMETSAT
