KSAT - Library Tab not Loading in Learner Experience

Resolved after 1 hour 43 minutes, affecting Console, on January 27, 2026.

postmortem Jan 30, 2026, 03:10 PM UTC

On Tuesday, January 27, 2026, from approximately 14:46 \(UTC\) to 16:22 \(UTC\), some users experienced issues with loading the **Library** tab of the Learner Experience \(LX\). This incident was caused when an update to the **Library** tab contained a code change that conflicted with another recent update. The conflicting code changes unexpectedly caused an error on the LX that was not detected by our automated testing and monitoring until both updates were deployed to the production environment. To resolve this issue, we rolled back the updates, and the LX returned to normal performance by 16:22 \(UTC\). To prevent this type of issue in the future, we updated the code to prevent the error when the update is redeployed. We also improved the testing and monitoring protocols. No data loss occurred as a result of this issue.
