  • Planned Maintenance: Changes of high risk or that may disrupt a published service should occur during the planned maintenance windows. (Scheduled for the least active time of day.)
  • Non-disruptive Maintenance: Virtualization and redundancy allow many non-service affecting changes to occur during regular business hours with little to no risk.
  • No Changes: Maintenance is not scheduled because if an issue occurs it can be difficult to reach essential staff during these standard commuting hours.
  • Emergency response only: Automated maintenance, such as OS or DB patching, and vendor maintenance outside of Cornell's control may occur. Other maintenance should be scheduled in the appropriate maintenance windows. Systems Support is available 24x7x365 for service affecting issues. Call the Service Desk at (607) 255-5500 and ask the staff member to connect you to the Systems Administrator on-call, noting that this request should be considered urgent.
