Web Services Scheduled Maintenance

One or more of the College of Literature, Science, and the Arts (LSA) web sites may be down for scheduled maintenance:

  • Weeknights between 11:00pm and 1:00am
  • Weekend scheduled maintenance, next scheduled for 8:00pm EDT Friday, October 23rd, and 12:01am Monday, October 26th, 2015

Service interruptions during these times, especially on the Saturday morning of weekend scheduled maintenance, are expected. We attempt to minimize user-facing disruptions but some cannot be avoided.

We tend to announce both maintenance and extended outages on our Twitter stream, @umlsait. Feel free to check there for more information.

We occasionally need to patch servers or restart services. We attempt to limit user-visible restarts to weeknights between 11:00pm and 1:00am, though for critical security patches we may be unable to do so. Any web service with "lsa.umich.edu" in its name may be affected during these outages, though on weeknights it is often only one set of services (for example, "CMS-based sites," "legacy web applications," or "SharePoint") and not all services. Most weeknight interruptions of service are brief, lasting 5 minutes or less, though major work may take longer.

During scheduled weekend maintenance, most sites will be affected at least briefly and some sites may be affected for long periods of time.

The sites which should automatically get to this page during outages include:

  • If this message appears outside regular business hours and outside one of the maintenance windows discussed above, you can contact the ITS Service Center (at 734.764.HELP or 4help@umich.edu) and, for CMS and SharePoint sites, they may be able to escalate the issue to on-call staff.

We apologize for any inconvenience.
