PeopleSoft Availability Schedule 

We know that some employees occasionally work in PeopleSoft's various systems after hours or on the weekend.  OSF schedules it's maintenance windows in advance to allow you to effectively plan your time.   Technically, the system is available from 7:00AM to 6:30PM, although barring an emergency, the system is generally available except for scheduled maintenance times.
