HTC downtime for maintenance TOMORROW Sep 30

[chtc-users@xxxxxxxxxxx]

Dear CHTC Users,

This message is for users of the High Throughput Computing (HTC) cluster, who log into any of the CHTC APs (including group owned APs). 

The APs will undergo maintenance TOMORROW, Tuesday Sept. 30, 2025. We expect the downtime to be resolved by the end of the day. 

If you are a CHTC user, during this time:

• You will not be able to log in.

• You will not be able to access your /home directory.

• You will not be able to submit new jobs.

• Your running jobs may be interrupted (but remain in the queue).

• Your idle jobs in the queue will not start.

This maintenance is to upgrade the APs for a security patch and address the ongoing quota mismatches issues.

We will post updates about the maintenance to the status page here: https://status.chtc.wisc.edu/incidents/4v9jrxsxl4cw 

Please direct any questions or concerns to chtc@xxxxxxxxxxx. 

Regards,

Your CHTC Team
