ITS Service Status Report

Scheduled Maintenance — Resolved

Slack Sign-In Maintenance (SSO Certificate Rotation)

Services Affected: U-M Slack

Start Time: 06/29/2022 5:00 pm

Maintenance Completed: 06/29/2022 5:19 pm

Issue Symptoms: None

Slack will be making routine security changes to the sign-in process that requires action from ITS so that members of U-M Slack may continue to sign in using U-M Weblogin after July 7, 2022.

This only impacts U-M Slack (not other Slack workspaces outside of U-M Slack), and only impacts U-M Slack full members (students, faculty, staff, and sponsored affiliates); it does not impact guests.

It is expected that there will be little to no impact on U-M Slack users as a result of this maintenance. It is possible that U-M Slack members who attempt to sign in to U-M Slack during the maintenance may be unable to do so; if so, it is advised to wait 10 minutes and try again. Those who are already signed in will experience no impact.

Who is Impacted? Members of U-M Slack who attempt to sign in to U-M Slack during the maintenance

Next Update: Wednesday, June 29, 2022, 5:30 PM
