Learn@UW - Possible Problem with Early Morning Logins and Other Functions

If you log onto a Learn@UW site and attempt various functions such as taking a quiz between midnight and 7 AM, there is a chance you will receive an Internal Server (HTML 500) error or experience slowness. This is because various maintenance operations may be in progress during these times.

Here is the weekly schedule for maintenance operations:

Every day midnight - 12:30am Backups
Every day 1:45am - 5:00am Integration processes: course creation and enrollment processing
Every day 2:00am - 4:00am Database maintenance jobs
(all UW campuses except Milwaukee)
Every day 4:00am - 5:00am Database maintenance jobs
(UW-Milwaukee)
Thursday 5:00am - 7:00am Weekly standing maintenance window

If you receive an internal server (500) error or experience slowness while maintenance is in progress, try logging in again or attempting your function later after a short delay, or wait for the end of the maintenance operation period.
