ISP Outage Detector

Detect potential ISP or regional outages using reachability checks, a live anomaly heatmap (CAIDA IODA), location-based context, and incident notes — built for help desk and NOC troubleshooting.

The ISP Outage Detector helps you answer the two questions that matter during an incident: “Is it just me?” and “Is this regional / ISP-wide?” It combines fast reachability checks to major networks, a location-aware map, local notes, and a live anomaly heatmap (CAIDA IODA) so you can triage issues quickly without guessing.

Use this when you see sudden disconnects, widespread slowness, login timeouts, streaming/VPN failures, or “everything is slow” tickets. It’s designed to help help desk and NOC-style troubleshooting: gather evidence, verify symptoms, and decide whether to escalate internally or open a provider ticket.

Tip: drag windows by their title bars. Use the taskbar to show/hide windows. Submit reports to color the heatmap.
