ow I approached it: Review Log and Monitoring Data: I started by analyzing the production logs to identify any error messages or unusual behavior. I also checked our monitoring tools to see if there were any anomalies in system performance metrics like CPU usage or memory. Collaborate with Cross-Functional Teams: Since our processes often depend on other systems, I reached out to the IT and business teams to gather insights. Together, we identified that the issue was related to a dependency on a third-party service that had recently updated its API. Attempt to Stimulate the Issue in Test: I tried to replicate the exact conditions in our testing environment, including using the same data and configurations. By systematically changing variables, I was able to pinpoint the root cause—an outdated API endpoint in our code. Document Incident, Root Cause, and Steps Taken: I documented the entire incident, including the root cause and the steps I took to resolve it. I also noted lessons learned, such as the importance of regularly updating API endpoints in our code.
