We will be conducting network maintenance on Tuesday, December 16, at 7:00 AM EST to prepare for the January 6 scheduled downtime. There is a low probability of brief disconnection for external connections (SSH/OnDemand) to the HPC environment. Running jobs will continue to run. We expect this operation to be seamless.

A downtime for OSC HPC systems is scheduled from 7 a.m. to 9 p.m., Tuesday, January 6, 2026. The downtime will affect the Pitzer, Cardinal and Ascend Clusters, web portals, the state-wide licenses and HPC file servers. MyOSC (the client portal) will be available during the downtime. In preparation for the downtime, the batch scheduler will not start jobs that cannot be completed before 7 a.m., January 6. Jobs that are not started on clusters will be held until after the downtime and then started once the system is returned to production status.

Globus services (including Auth, Transfer, Flows, Search, Timer, Compute, GlobusID, and Action Providers) will be unavailable for up to 1.5 hours beginning at 10:00 AM EDT on Saturday, November 2, 2024, due to planned maintenance. Transfers in progress at the start of the downtime will resume from the last checkpoint when services are restored.
