        Update -
      	Maintenance will begin as scheduled in 60 minutes. 
In preparation please:
* save any ongoing work
* terminate (using the bkill command) any interactive jobs that are running
* logout from your session prior to the maintenance window
Logins will not be possible during this time and running jobs will be affected, any jobs that are still running at the start of the maintenance window will be terminated and will need to be rerun.  This will include any orchestration jobs you may have running for your workflows.  
We will stop accepting jobs in the queues at the start of the maintenance period and expect there to be a drain of jobs in the short and medium queues that will result in running jobs being completed as expected.  Long running jobs within the long queue will be affected and will need to be rerun as there may not be time for these to drain.

        Update -
      	Dear research user, 
This is a reminder of the Double Helix HPC maintenance on 30 October 2025.
What to expect:
-Today 29 October 2025 - the short, medium, and long queues will be closed today at 10:00 GMT.  
This means you can still submit jobs but no jobs will be dispatched.
We anticipate that jobs submitted to the short and medium queues before this time will complete successfully. However, please note that some long queue jobs may be terminated prematurely and will need to be re-submitted after the maintenance.
-Tomorrow 30 October 2025 - login and compute nodes will not be available from 10:00 GMT and 14:00 (GMT).
We apologise for any inconvenience this may cause.
Best Wishes,
Genomics England

        Update -
      	To clarify what the impact is to the research user.
The Double Helix HPC's login and compute nodes will not be available on Thursday, 30 October 2025 from  10:00 (GMT) to 14:00 (GMT).
Logins will not be possible during this time and running jobs will be affected, any jobs that are still running at the start of the maintenance window will be terminated and will need to be rerun.  This will include any orchestration jobs you may have running for your workflows.  We have to take this action to perform an urgent security patch on our systems to ensure the security of our data and your work.  We will stop accepting jobs in the queues at the start of the maintenance period and expect there to be a drain of jobs in the short and medium queues that will result in running jobs being completed as expected.  Because of the window between this announcement and the start of this essential work it is possible that some long running jobs within the long queue will be affected and will need to be rerun as there may not be time for these to drain.
In preparation please:
* save any ongoing work,
* terminate (using the bkill command) any interactive jobs or long that are running,
* logout from your session prior to the maintenance window.
You may login and resubmit your jobs after the window.
A notification will be sent 24 hours before the maintenance window to inform users that jobs will be closed or drained ahead of scheduled downtime.
