Dear SciComp Users,
A scheduled outage is planned for Tuesday, September 23 through noon on Wednesday, September 24, affecting all farm nodes, including ifarm and JupyterHub.
Reason for Outage:
A failing disk shelf affecting the /work areas requires urgent replacement. During this window, we will also perform:

  *   Reboots across farm nodes

  *   Application of Maintenance Day (MD) system patches

  *   Firmware updates to farm19, farm23, sciml

Affected Systems:

  *   All farm nodes

  *   /work areas

  *   ifarm

  *   JupyterHub

Downtime Window:

  *   Start: Monday, September 23, 8am

  *   End: By noon, Wednesday, September 24

While we aim to restore services as promptly as possible, this extended outage window allows for:

  *   Safety of on-site personnel

  *   Proper hardware replacement and testing

  *   Confidence in system stability before resuming production

A follow-up "all-clear" notice will be sent when systems are fully operational.
We appreciate your understanding and patience during this essential maintenance.
Best regards,
Scientific Operations Team
