Our schools Canvas site seems to be down. Any ideas as to the cause or a time when it may be back up? The site is cehe.instructure.com
Because this is a global community whose members don't have access to the specifics of your school's servers or status, we recommend that you reach out directly to the school to obtain updates. "CEHE" sounds like it might be Center for Excellence in Higher Education » Helping Donors Transform Higher Education Through Effect... —there's a phone number there—and since your email address is associated with Independence University, you might also try the contact information at the bottom of this page: Student Help & Support | Independence University
Hope this helps.
You have actually posted to the global Canvas Community where people come together from all over to collaborate on how to best use Canvas.
If you're still having issues I would suggest contacting your local support or #canvas support for additional assistance as we in the community do not have access to your instance of Canvas.
I can tell you that I was able to use the URL you provided and was able to bring up your schools Canvas login page.
