Incident Description

On 2025-04-03, between 7:30 and 12:17 UTC, the SAP LeanIX MS Teams Chatbot experienced an outage due to a misconfiguration in the deployment. This impacted all users of the Microsoft Teams application, and during this period, users were unable to receive responses to queries submitted to the SAP LeanIX MS Teams Chatbot.

Incident Resolution

We deployed a fix with the correct configuration, bringing the service back online. The SAP LeanIX MS Teams Chatbot is now functioning as expected.

Root Cause Analysis

The outage occurred after we deployed changes to production that included a misconfiguration in the deployment configuration, which led to the service disruption and SAP LeanIX MS Teams Chatbot downtime.

Preventative Measures

To prevent similar incidents in the future, we aim to improve in the the following areas:

• We will enhance the tests to detect the failures in the deployment configuration files
• We will invest more in monitoring and alerting to catch deployment configuration failures
• We will improve the mitigation process to ensure a quicker response time
