Date and Time	Description	Services Affected	Expected Impact	Notes
2025-09-17 10:00-15:00 local	Image update to be applied to login and compute nodes	Isambard-AI Phase 2 Compute Service	System will be unavailable during the period. A reservation will be used to drain work prior to the image update. Connections to the login nodes will be severed at 10am and login node access will not be possible until the image update is complete. Please ensure any work is saved and sessions disconnected before the planned start time.	During this change the storage system used for your /home directory will change. Your new home directory will be created the first time you login after this change and will be empty, but your previous home directory will still be available at /lus/lfs1aip2/home/<PROJECT>/<USER>.<PROJECT> for you to copy its contents. We will not proactively copy data across and you should be aware that the new /home will have a smaller quota. Please see the Storage spaces documentation for details on available areas to store data.
