• Post-Mortem

  From 15:30 BST on 10/06/2025 until 11:20 BST on 11/06/2025, Learn mistakenly sent course deadline reminder emails to managers and tutors outside of their configured notification schedules. Emails could have been received after this time as they worked their way through email servers to reach their recipients. In some cases, managers and tutors received emails even where their own notification schedules had been disabled. The content of all emails was accurate, relating to genuine unmet course deadlines, however the recipient logic did not reflect individual customer configuration.

  The issue was caused by a deployment on the afternoon of 10/06/2025, which included changes to improve the performance of course deadline reminders and to extend refresher training (lesson set) logic to manager and tutor emails. During this deployment, manager and tutor email jobs were incorrectly configured to reference the end-user notification schedule rather than their own dedicated schedules. Email notifications were suspended on the morning of 11/06/2025 whilst the issue was investigated, however the main batch of morning reminder emails had already been processed before this action was taken. Once the root cause was confirmed, the changes were rolled back in full and email notifications were re-enabled.

  Although we know the precise cause of this issue, the deadline reminder changes will be reviewed and tested thoroughly before being redeployed. We apologise for any disruption caused and thank you for your patience while we worked to resolve this.

• In Progress

  Engineers are actively investigating and working to resolve an issue with email notification scheduling across Kallidus products. Customers using course deadline reminders may be receiving emails outside of their expected schedule. We have temporarily disabled all email notifications to prevent further messages entering the queue whilst we resolve the issue — any emails already processed may continue to be delivered over the next 1–2 hours. We have identified the root cause and are working to deploy a fix as quickly as possible. We apologise for any inconvenience caused.
