Investigating
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.
