Udemy Outage History

Udemy experienced a major incident where lectures could not be marked as completed even after users watched the full content, affecting both Udemy Business and Udemy.com platforms. The issue lasted 24.6 hours and impacted course progress tracking across the entire service. While the core problem was resolved, users who completed courses during the incident may still see incomplete status, with Udemy working on automatic backfill processes and offering manual support for urgent cases.

Udemy's Labs feature experienced stability issues that prevented UB Pro users from launching labs in Practice mode, specifically affecting Jupyter Notebook Labs. The engineering team identified and addressed the root cause of the stability problems after investigation. The incident was fully resolved after 4.8 hours of downtime, with the system confirmed stable and operating normally.

Udemy experienced a 27-minute service disruption where course landing pages failed to load for Market Place and Personal Plan Grow with Google subscribers, while other users experienced slow loading times across parts of the site. The issue was caused by a recent change that the engineering team identified and reverted. Course landing pages were restored to normal loading speeds, with Udemy Business users remaining unaffected throughout the incident.
