Partner Service Outage May Disrupt Learnosity API Initialization in All Regions

Update timeline

1. investigating Oct 02, 2025, 09:34 PM UTC

   As of 21:15 UTC, Learnosity APIs are being impacted by a temporary outage from our Math partner, Desmos. Authoring or Editing content with Desmos questions or features, or initializing assessments that contain Desmos questions or features, can prevent the Author API or Items API from initializing. Specific reports that display question content, such as the Session Detail by Item report, can also fail to initialize Learnosity APIs are not otherwise impacted, so content that does not include Desmos features are not affected. Until we learn more, we will list APIs that may experience knock-on effects from this temporary Desmos outage. However, as most customers will not experience any issues, we will not list these APIs as down. Desmos and Learnosity Support and Systems Engineering teams are actively investigating the issue, and will follow on with an update and resolution as soon as possible.

2. monitoring Oct 02, 2025, 10:14 PM UTC

   As of 22:12 UTC, Desmos services have been restored and Learnosity APIs are initializing without issue. Desmos and Learnosity Support and Systems Engineering teams will continue to monitor for a further 30 minutes before declaring this issue resolved. We will follow on with an update and resolution as soon as possible.

3. resolved Oct 02, 2025, 10:43 PM UTC

   As of 22:42 UTC, all Learnosity APIs are continuing to function as expected in all regions, and we are declaring this issue resolved. Learnosity Support and Systems Engineering teams will follow up with a post mortem once we have completed root cause analysis and finalized any next steps or preventative measures required. Please reach out if you have any questions or concerns.
