During this time, the Github appliances will receive normal software updates, and you may have difficulties accessing your repositories.

During this time, Fortress will receive normal software and hardware updates. Any transfers which request files sent to or from Fortress will either block or fail until this maintenance is completed.

Users may be unable to browse directories or start new transfers involving this endpoint. There is no workaround at this time other than retrying later or using an alternate endpoint when possible. Our next update will be posted on or before 11:00am Thursday 4/30/26 or sooner.

During this time, the Github appliances will receive normal software updates, and you may have difficulties accessing your repositories.

During this time, Fortress will receive normal software and hardware updates. Any transfers which request files sent to or from Fortress will either block or fail until this maintenance is completed.

Service was fully restored at 10:45 PM EDT, and login functionality has returned to normal. No data loss occurred.

To prevent further impact, job submissions to clusters connected to Depot have been temporarily paused while the team works restore normal operation.

Impact: Users may experience job delays or failures when writing to the Data Depot.

Current Status: Our engineering team is actively addressing the capacity issue.

Next Update: We will provide an update once the service is restored or we have more information to share.

The Weber cluster will be unavailable Wednesday, March 18, 2026 from 8:00am - 5:00pm EDT for scheduled maintenance. The cluster will return to full production by 5:00pm EDT.

During this time, Weber will have its operating system patched.

Any Slurm jobs which request a walltime which would take them past Wednesday, March 18, 2026 at 8:00am EDT will not start and will remain in the queue until after the maintenance is completed.

Due to the outage, some jobs on Gilbreth did not requeue automatically. Users should check the status of any jobs that were running early this morning and resubmit them if needed.

• Impact: Users are currently unable to access their home directories, and SSH connections or active terminal sessions may freeze or be denied.

• Current action: System administrators are performing a system reboot of the affected storage infrastructure to clear the error and restore file access.

** How does this change impact you? **

Login to Weber: The change will simplify logging into Weber. Weber users currently need to authenticate to Luna VPN or VDI with Luna credentials, and then additionally authenticate to Weber with BoilerAD credentials. After the change, users will just need to use their Luna password when logging into Weber resources, including via ThinlLinc, SMB, and SSH. Luna password will be the same password as is currently used to log into the VPN.

ThinlLinc: Anyone accessing Weber via ThinLinc directly from their endpoint will need to switch to using ThinLinc from a Luna Desktop.

Data Egress: File egress will be disabled, and users will need to submit a ticket each time they wish to transfer files outside weber. Egress to Apricon drives will no longer be supported on regular endpoints.

During the maintenance window, job scheduling though Slurm and network drive mounts of Weber storage will be unavailable.

These changes position Purdue to meet the requirements of CMMC Level 2 compliance and will be crucial for continuation of various grants and contracts.
