On Wednesday, August 19, 2026, at 5:00 pm CDT, IT will be updating a set of security certificates. This change is part of a planned transition with our certificate provider and is intended to keep our network authentication secure and running smoothly.
What this means for you:
For most devices, this update will happen automatically in the background, and no action will be needed on your part.
- Windows devices: In most cases, this update will apply automatically with no interruption. If any issue arises, IT will follow up directly with affected users.
- Mac devices: You may see a prompt asking you to “Trust” a new certificate when connecting to the network. If you see this prompt, please select Trust to continue uninterrupted access.
If you experience any issues connecting to Wi-Fi or the network on or after August 19, please contact the ITS Service Desk at 901.448.2222.
Thank you for your patience as we continue working behind the scenes to keep UT Health Sciences’ network secure.
