Scheduled Maintenance — Resolved

Upgrades to Shibboleth infrastructure

Services Affected: Upgrade Shibboleth version from v3.7.2 to v4.0.1

Start Time: 11/21/2020 11:00 pm

Maintenance Completed: 11/22/2020 12:19 am

Issue Symptoms: Intermittent issues

During this maintenance window, the IAM Operations team will be making upgrades to the Production Shibboleth environment. This includes a Shibboleth software version upgrade from v3.7.2 to v4.0.1, as well as an operating system upgrade from the current Red Hat Enterprise Linux v6 servers to new RHEL v7 servers.

We will be adding the new servers alongside the existing servers, and then removing the old servers, the same way we do all other configuration updates to Shibboleth. This minimizes impact to end users. The only side effect of the upgrade is that some users may need to re-authenticate to weblogin.umich.edu once the cutover to the new servers is complete.

Who is Impacted? All users accessing services protected by weblogin.umich.edu and/or shibboleth.umich.edu

Next Update: Sunday 11/22 after the maintenance is completed
