ISP incidents remain one of the fastest ways to impact user experience and one of the hardest to prove quickly. In this session, we’ll walk through a real customer example and show how we detected an ISP issue early by comparing user-to-app path performance across regions and ISPs. We’ll also cover how “peer” telemetry (crowd signals across many environments) can help you validate whether an issue is inside your network, at an ISP, or specific to a single site.
We’ll focus on the practical workflow: spotting the anomaly, confirming it’s an ISP event, narrowing blast radius, and taking action—like rerouting users to a healthier egress/data center—to cut troubleshooting time dramatically.
