Maintenance: Block Storage Service Upgrade

Start: 2026-02-23 10:00 CET

End: 2026-02-23 14:00 CET

Duration: 4 h 0 min

What: We will be applying an update to the OpenStack Volume API (Cinder).

Impact:
Throughout the maintenance period, the API may occasionally respond slowly to your requests.
The availability and access to already created and mounted volumes is not affected.

What you need to do:
Block Storage (Cinder) v2 API will be removed. Update your clients to use Block Storage (Cinder) v3 API which is backward compatible with the v2 API.
We recommend planning changes to critical operations that depend on the volume service outside the maintenance period.
