Dual-WAN Failover Monitor for Windows

ClumsyLinkWatch · Clumsy's Lab

The failover numbers you currently have to guess at.

Running two WAN connections — a UDM/UCG, pfSense, or a router with a failover script — tells you failover happened. It doesn't tell you how long it took, how often it happens, or whether WAN2 is actually pulling its weight. ClumsyLinkWatch tracks all three on a Windows box on your LAN, no enterprise NMS required.

What it actually measures

ClumsyLinkWatch periodically resolves your public IP and records a WAN-state change whenever it shifts. A public IP change with no connectivity gap in the timeline means a clean failover. A change with a gap means the failover took a measurable number of seconds — that number is what most dual-WAN setups currently can't produce without building it themselves in Uptime Kuma plus guesswork.

Per-WAN uptime

Reported separately per WAN, not blended into one number that hides which link is actually carrying the reliability.

Failover count & mean duration

How often failover triggered over a period, and how long it typically takes — the two numbers people want and currently can't get.

Full evidence timeline

Every WAN-state change sits on the same time-proportional timeline as every other detected event, sleep gaps included and excluded correctly.

Homelab-built, homelab-tested This capability exists because the person building ClumsyLinkWatch runs it personally on a UCG-Fiber with ConnecTen/T-Mobile as WAN1 and Starlink as WAN2 — it was built to answer a question about their own setup first.

Who this is for

Dual-WAN homelabbers

Running two ISPs behind a UDM/UCG, pfSense, or OPNsense box and want real failover history instead of building it from Uptime Kuma and guesswork.

Starlink as backup WAN

Starlink telemetry is built in separately — dish alignment, obstruction map, and its own event log — if Starlink is one of your two links.

Small IT consultants

Drop it at a client site with dual WAN, leave it for a week, and get a report that actually shows whether the failover setup is doing its job.
