19	19	The storage back-end used by HBP/EBRAINS services has been causing some issues which have had repercussions on access to the object storage and OpenStack cloud service and thereby on HBP/EBRAINS services which run on this infrastructure. The issue has been identified and CSCS is ready to deploy a patch on the storage back-end. This will require that services running on OpenStack at CSCS be stopped for the duration of the maintenance.
