On Friday, October 10, 2025, from 8:30 AM to 10:30 AM ET, the backend Drupal interface will be temporarily unavailable for all website editors who log in via SSO (Single Sign-On - DUO). This downtime is necessary to perform essential maintenance and security updates.
If urgent website edits are required during this period, OISE community members are encouraged to contact the OISE Drupal Website group through the OISE Online Service Hub. Admins will still have access and can make critical updates as needed.
Once the upgrade is complete, regular editing access will resume, and site editors can continue updating their websites as usual.

On August 25, 2025, the University of Toronto's central networking team updated the security certificates for all wireless networks across St. George Campus. This change affects Wi-Fi connectivity at OISE, JICS, and 371 Bloor Street West, and will impact members of the OISE community trying to connect to the wireless network.
Depending on your device, you may need to make minor adjustments to reconnect:
Mac Devices (including iPhones and iPads)
- You will be prompted to re-enter your password.
- After entering your password, your device should reconnect automatically.
- You may also need to confirm trust in the new network certificate.
Windows Devices (including Android phones)
Some users will be prompted to re-enter their password. If not prompted, follow these steps:
- Forget the UofT wireless network.
- Reconnect to the network.
- Enter your UTORid credentials again.
For detailed instructions based on your device, please refer to the or contact Education Commons for further assistance.
From June 2 to July 31, 2025, OISE community members using the wired network at 252 Bloor Street West may experience temporary interruptions and connectivity issues. These disruptions are due to ongoing upgrades by the central University of Toronto IT team, aimed at improving the stability, reliability, and performance of our wired network. The OISE and University of Toronto wireless networks will remain unaffected during this period.
To minimize disruption, Education Commons encourages all OISE community members visiting the OISE building to switch to the wireless network if they encounter any wired network issues/dropped connections. Additionally, onsite display screens (DTEN and departmental OptiSigns) will be temporarily configured to operate over the wireless network.
We appreciate your patience and understanding as the University of Toronto works to enhance our building network infrastructure for the benefit of the entire OISE community.
Departmental Notice: Updates to virtual display screens (OptiSigns) may be slower than usual while these changes are in effect.
