The ITS System Status Page provides an overview of current service status messages and scheduled maintenance for major University of Toronto systems and services. You may contact the Joint Operations Group (JOG) using the e-mail link above or by calling 416-978-4621. The JOG is staffed Monday to Friday, 8am-4pm.

Please scroll down to see details of upcoming scheduled maintenance as well as historical information on previous incidents.

We recommend that you sign up to receive push notifications of service outages. Click on the "Subscribe to Updates" button at the top of this page and select the method(s) by which you want to receive system status updates. For e-mail notifications, we recommend using a non-UofT email address so that you will still receive notifications in the event there is an outage that prevents access to university email services.

Update - Mitigation Implemented – Services Restored
Authentication and core network services have been successfully mitigated following targeted infrastructure adjustments. Connection queues and performance delays have cleared, and systems (including Weblogin,Duo and UTORvpn) are fully accessible. While primary operations are restored and performing normally, engineers are maintaining an active workaround while awaiting final hardware maintenance to re-establish full redundancy. Technical teams will continue heightened monitoring, but no further service impacts are expected at this time.
