Overview of the Incident
On October 20, 2025, a significant outage of Amazon Web Services (AWS) disrupted access to Canvas, a widely used learning management system (LMS) across numerous educational institutions in the United States. The outage began around 2 a.m. ET and affected students and educators nationwide, preventing them from accessing course materials, submitting assignments, and communicating through the platform.
Impact on Educational Institutions
Canvas, owned by Instructure, is integral to the academic experience for many students and faculty members. The outage has been reported at various institutions, including Rutgers University, Indiana University, Mississippi State University, and Tulane University. Students encountered error messages such as "502 Bad Gateway" and "Canvas failed to load," leading to significant disruptions in classes and assignments. For instance, Indiana University students reported canceled classes and inability to access vital course information, while Tulane University noted that midterm exams were postponed due to the outage.
Technical Details of the AWS Outage
The AWS incident was attributed to internal network issues within Amazon's Elastic Compute Cloud (EC2), which is responsible for hosting numerous applications, including Canvas. AWS confirmed that the problems originated from a malfunction in their internal monitoring systems, which led to widespread connectivity issues. As of 1:03 p.m. ET, AWS was actively working on recovery efforts, stating they were "validating a fix" for the EC2 launch failure.
Official Statements & Responses
Instructure, the company behind Canvas, acknowledged the outage and stated they were collaborating with AWS to restore services. They began investigating the issue at 3 a.m. ET and confirmed that the outage was due to the AWS incident. Various universities communicated with their students, advising them to reach out to instructors regarding assignment deadlines and alternative communication methods during the disruption.
Student Reactions and Experiences
Students expressed frustration over the outage, particularly as it coincided with critical academic activities. Many reported being unable to access assignments or communicate with instructors. For example, one Indiana University student noted that their calculus assignment was due shortly after the outage began, while another student at Lindenwood University highlighted the impact on their ability to order food during class breaks due to the simultaneous Grubhub outage.
Criticism & Opposition
Some students and faculty members voiced concerns about the reliance on cloud-based systems like Canvas, emphasizing the need for backup plans and alternative methods of communication during outages. An associate professor at Columbia University suggested that the incident highlighted the dependency on technology in education and called for a reevaluation of how institutions manage such disruptions.
Conflicting Reports & Gaps
While AWS reported that they had resolved issues for 38 services, over 100 services remained affected as of the latest updates. The exact timeline for when Canvas and other impacted services will be fully restored remains unclear, with ongoing efforts to mitigate the issues.
Conclusion
The AWS outage on October 20, 2025, has underscored the vulnerabilities associated with cloud-based educational platforms like Canvas. As institutions work to navigate the disruptions, the incident raises important questions about the reliance on technology in education and the need for effective contingency plans.
