On July 22, 2024, at 11:04 AM CET, an incident was initiated when the email signature synchronization process took longer than usual to complete, causing delays in distributing email signature updates to end users. The engineering team quickly initiated an investigation and identified that the issue was caused by message processing. The problem arose due to a recent migration to a new messaging framework, which began to exhibit performance issues. To mitigate the problem, the team reverted to the previous messaging framework, confirmed that the synchronization was running within the desired parameters, and by 1:07 PM CET, managed to deploy the fixed version to all production environments. The team continued to monitor system performance and, after ensuring everything was operating at the desired performance metrics, marked the incident as resolved at 6:27 PM CET. The engineering team is currently conducting extensive tests to identify the root cause of the performance issues in the new messaging framework. Additionally, they are focusing on further quality automation and performance checks to prevent similar incidents in the future.
