As of 13:20 UTC, we started seeing scoring delays with our Enhanced Math Scoring service in the US-East-1 region. No data loss has been observed and all sessions have ultimately been scored. As a knock-on effect, the Data API Scoring endpoint is experiencing intermittent availability issues. No authoring or assessment delivery has been affected. Learnosity Support and Systems Engineering teams are actively investigating the issue, and will follow on with an update and resolution as soon as possible.

As of 15:00 UTC, we are still investigating the short-lived degraded performance of our Enhanced Math Scoring service, but have not seen significant errors or delays for more than an hour. The backlog of sessions awaiting scoring cleared quickly, and submissions continue to be scored normally. All other APIs remain unaffected. 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.
