Alert: Canvas Outage Update
Canvas access has been restored for our users, but the service reliability remains uncertain. Due to recent events, Canvas has had intermittent outages which are at the discretion of the vendor and may occur during a final exam. Faculty and staff may continue to use Canvas, but we strongly advise faculty and students to prepare a contingency plan for turning in assignments and final exams in the event Canvas access becomes unavailable again.
Instructure, the company that owns Canvas, has provided an FAQ about the incident, which may not answer all your questions. We will share more information if it becomes available.
