[Admin Tools] Allow teachers to temporarily block access to their Canvas site during exams
Some of our faculty wish to block access to their Canvas sites during the administration of exams. Currently our solution is to have them manually adjust the start/end dates of the course and block student access outside of those dates. Once the exam is over, they need to go back in and remove the dates and restrictions. This approach is error-prone and is further complicated by the fact that our SIS feed may overwrite the manually-set dates unexpectedly.
A better solution would be for Canvas to let the teaching staff specify temporary blackout periods during which students would not be allowed to access the site (using either a computer or mobile device). Ideally the person configuring the block would be able to include a custom message to be displayed.
The ability for teachers to use this feature could be controlled by an account-level setting, similar to the "Don't let teachers modify course availability dates" setting.
