  1. investigating Jan 12, 2026, 05:06 PM UTC

    As of 4:30 UTC, we are currently investigating an issue that may result in temporary session unavailability for a small number of US-only customers. We can confirm that no session data has been lost, and we are working to restore the affected sessions as quickly as possible. 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. identified Jan 12, 2026, 05:52 PM UTC

    As of 5:30 UTC, we've identified and corrected a load balancing configuration affecting database reads and writes for a very small number of US-only customers with consumers in the US-East-1 region. - All new sessions will behave as expected. - Read requests seeking data on sessions created prior to 23:00 UTC yesterday will also now behave correctly. - We are working on restoring sessions recently affected While all APIs continue to function normally, this update identifies service areas that may temporarily have limited access to recently saved or submitted sessions. Learnosity Support and Systems Engineering teams are continuing to actively investigate the issue, and will follow on with an update and resolution as soon as possible.

  3. resolved Jan 12, 2026, 07:10 PM UTC

    As of 7:00 UTC, we've concluded our monitoring and confirmed that all new requests are behaving as expected. We are closing this record and will continue to work with affected customers directly to confirm that all recent sessions are accessible. Please reach out if you have any questions or concerns.

  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.

Notice August 8, 2025

Possible Issue affecting manual updates to session data in US-East-1 (VA) region

Affected: Updating session response scores
Timeline · 4 updates
  1. investigating Aug 08, 2025, 01:55 PM UTC

    As of 13:40 UTC, we began investigating a possible issue affecting manual update jobs to session response scores, sessions statuses, and session metadata in the US-East-1 (VA) region. We saw a brief buildup in the queue for these jobs, the queue processed as expected, and is now empty. However, we're investigating further, out of an abundance of caution, to see if there are any unexpected causes for the short queue buildup. 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. investigating Aug 08, 2025, 01:57 PM UTC

    As of 13:55 UTC, all manual update jobs have been executed and the jobs queue is empty. Requests to manually update session response scores, session statuses, and session metadata should execute as expected. We are still investigating possible reasons for the blip. Learnosity Support and Systems Engineering teams are continuing to actively investigate the issue, and will follow on with an update and resolution as soon as possible.

  3. resolved Aug 08, 2025, 02:19 PM UTC

    As of 14:10 UTC, we've found no negative behavior in the manual update processes and attribute the short burst of jobs to uncharacteristic testing of the new manual grading workflow. The jobs queue functioned as expected, ensuring no loss of requests, and the jobs were processed in a timely fashion. Learnosity will continue to monitor this activity for a further 60 minutes, but we are calling this resolved at this time. We apologize for the unwarranted alert. Please reach out if you have any questions or concerns.

  4. postmortem Aug 08, 2025, 02:19 PM UTC

    At 13:40 UTC on 8 August 2025, we noticed a brief backup of asynchronous jobs affecting manual session updates in the US-East-1 \(VA\) region. Possible jobs including manual updates to response scores, session statuses, and session metadata. The queue mechanism worked as expected, and all requests were processed in short order. Out of an abundance of caution, we raised an alert while systems remained operational, but found nothing of concern during our investigation. We hope the unwarranted alert was not a significant distraction.
