Update May 7, 2026 | 5:30 p.m. MST We are aware of a cybersecurity incident involving Instructure, the parent company that operates our learning management system, Canvas. This incident has reportedly affected Canvas users at education institutions worldwide. At this time, we are actively reviewing information from Instructure and working with our information technology team to determine additional details regarding the breach. Information that may have been accessed include names, email addresses, and student ID numbers. No passwords, dates of birth, government identifiers, or financial information were involved in this incident. At this time, students, faculty, and staff are unable to access Canvas. It is unclear whether the loss of access is related to unauthorized activity or whether access has been temporarily restricted by Canvas/Instructure as part of its response. We know this comes at a time when there are important academic deadlines, assignments, and final exams and projects. We are working through individual instructors to determine next steps, as we do not know the extent or timeline of this incident. We ask that you please communicate directly with your instructor regarding all end-of-semester items. While we do not know the full extent or timeline for this incident, please know that our celebration of students on Saturday, May 9, 2026 will continue as planned. -Dr. Walter Tribley, President

Update May 8, 2026 | 9:21 a.m. MST Access to Canvas has been fully restored for all of our users. We have been in direct communication with Instructure, Canvas’s parent company, which has confirmed that our Canvas system is now fully operational and available for use. We hope this access will continue, but we will continue to work with Instructure and cannot guarantee that there will be no future disruption. Instructure also indicated through communication with us that there is no evidence that the unauthorized actor obtained account credentials within our institution or accessed additional data. While this is encouraging news, the disruption serves as an important reminder of both the vulnerabilities of technology and the need to maintain appropriate safeguards and backup plans. As an institution, we are reviewing and strengthening our processes based on what we have learned from this incident. I want to sincerely apologize to those who were unable to access Canvas during finals week. I understand that this may have caused stress or uncertainty, and I regret the impact this disruption had on your work. For students with upcoming final exams or project deadlines, Canvas should now be functioning normally. Please continue to communicate directly with your instructors regarding any specific course expectations and to ensure all requirements are completed. We will continue to monitor the situation closely and will provide additional updates if necessary. -Dr. Walter Tribley, President

Message elements

How the first alert is built

To check this alert, SuperGrok Heavy 4.5 (an AI) read it in full 25 separate times, independently. Each read decided whether the message answers each of the six questions and gave a short reason. A final reviewer then weighed all 25 and wrote the plain-English verdict you see when you open a row. The score (for example 22/25) is how many reads agreed; the 25 individual reads are tucked underneath if you want to check them.

  • Sourcepresent25/25

    Final assessment

    Source is present on 25 of 25 passes.

    Who is sending the alert and who is responding. People act faster on a message from a clearly identifiable, credible sender, such as a named department, the police, or a branded alert system, than on an anonymous notice. A branded signature counts.

  • Hazardpresent25/25

    Final assessment

    Hazard is present on 25 of 25 passes.

    What the threat actually is. A complete warning names the specific danger, such as a shooter, a fire, a tornado, or a gas leak, rather than a vague emergency, because people decide what to do based on what they are facing.

  • Locationabsent0/25

    Final assessment

    Location is absent on 0 of 25 passes.

    Where the threat is. Saying whether danger is in a specific building, a part of campus, or area-wide lets people judge their own proximity and choose a safe direction. Without a where, a warning is hard to act on precisely.

  • Guidancepresent25/25

    Final assessment

    Guidance is present on 25 of 25 passes.

    The protective action to take. A clear, specific instruction, such as shelter in place, evacuate, avoid the area, or run-hide-fight, drives faster and more correct protective behavior than describing the threat alone.

    Final assessment

    Time is present on 25 of 25 passes.

  • Impactpresent25/25

    Final assessment

    Impact is present on 25 of 25 passes.

    What the hazard could do to the people in its path. Beyond naming the threat, a complete warning conveys its potential consequences or severity, such as that a tornado can level buildings or that a leak could be explosive, so recipients grasp how much danger they are in. Research on warning message content finds that a concrete impact statement helps people personalize their risk and act sooner.
