Planned Data Center Outage for August 4-5

ISC has scheduled a data center outage for Saturday, August 4. The 3401 Walnut Data Center, which houses a number of critical University applications and services, will be taken off-line for activities associated with the migration and decommissioning of the facility. It is expected that the full 48-hour maintenance window will be necessary: August 4, 12 a.m. through August 5, 11:59 p.m.

During this 48-hour maintenance window, please note:

  • Clients potentially impacted by the outage will be contacted by the appropriate ISC service owner. The availability during the outage of a number of important and widely used applications and services will be posted at This list will be updated as we approach the outage date.
  • Applications and services that will be taken off-line or that may experience brief disruptions will be dependent on their migration status. Clients should contact the appropriate ISC service owner for the migration status of their applications housed at 3401.
  • Online mainframe applications and services that will not be available during the outage are: Payroll, Salary Management (SALMGMT), Student Financial Subsystems (SFSEASI), Student Aid Management (SAM, SAMS), Student Records System (SRS), Table and Data Dictionary (TADD). This is not a definitive list. Additional applications may be unavailable as we approach the outage date.
  • All regularly scheduled production batch jobs and sequences will be held during this time.

Planned outages are required for maintenance of the technology infrastructure that supports University systems. Postponing these activities is not an option, as it carries the risk of an unplanned disruption that would require extensive emergency recovery time and could have severe consequences for service availability. While there is never a perfect time for the data center to be off-line, we have scheduled all outages for weekends and on dates that are the least disruptive to significant campus events in the University’s calendars.

As in similar outages, we ask that you do not schedule system-dependent events during this time. 

ISC will hold two information sessions for the August outage. Look for details about the sessions, including registration, at

For questions, contact your regular application support resource or Local Support Provider (LSP). If you don’t know who your LSP is, see

Thank you for your patience and understanding as we continue to improve ISC services at Penn.
