Update: As of 6 p.m., Canvas is back online. It is unclear if all affected services have been restored. 

Thousands of websites and apps, including Canvas, a learning management software used by Tulane University, and Snapchat, a popular social media app, were knocked out Monday after an outage at Amazon Web Services. 

AWS provides services for 30% of the cloud computing market. Amazon said it has identified the issue and is applying mitigations to zones within the US-EAST-1 region, one of AWS’s largest and most critical data center clusters, where the outage originated. 

It is unclear when services will resume. AWS said it is confident that as mitigations are rolled out, launch errors and network connectivity issues will begin to subside. 

An email from Tulane University Information Technology encouraged students to check their Tulane emails for updates and save copies of any assignments being worked on. Tulane IT will send an update once service is restored.

Instructure, the company behind Canvas, said they are working with AWS to restore services.

A similar outage starting on the East Coast occurred in July 2024, affecting more than 2,000 companies worldwide. The outage lasted seven hours.

This is a developing story and may be updated.
