Authentication Service Disruption, Scheduled Downtime

This morning, September 29, from approximately 7:20-7:50 a.m., users were unable to log in to U of M Google Apps. This service disruption was caused by issues with the authentication service.

The Office of Information Technology (OIT) is aware of ongoing issues with authentication. They have been experiencing heavy loads, and have been working to mitigate the service disruption as much as possible.

In order to prevent further incidents such as the one the University experienced this morning, OIT is scheduling recurring maintenance on authentication. Beginning Friday, September 30, maintenance will be completed daily from 6:30 am-6:40 a.m. During that time, users will be unable to log in to applications that require authentication. These include Google Apps and Moodle. Users who are already logged in will not notice any service disruption.

While this short-term fix presents an undesirable service impact, it is intended to minimize service impact while OIT investigates a more permanent and satisfactory solution that addresses the root cause of this issue.
