In my previous role, we experienced intermittent network outages affecting critical business applications. Initial diagnostics showed no hardware failures, and basic troubleshooting didn’t reveal the root cause. I performed a deep packet analysis using Wireshark and discovered high latency due to asymmetric routing. I collaborated with the security team and identified an incorrect firewall policy causing asymmetric traffic flow. After implementing the correct routing policies and adjusting firewall rules, the issue was resolved. This experience reinforced the importance of in-depth analysis and cross-functional collaboration in troubleshooting complex network issues.
