Where does IC2 WAN Quality Latency come from?

Where does IC2 latency info come from? The screenshot below shows 1 of 4x VSAT WANs on a Balance One, showing ~3 ms latency, which is quite impossible on a VSAT link and totally incorrect.

The Balance One recently replaced a B20 with 3x VSAT links on v7 firmware. The B20 never had this issue in IC2 and latency was always reported correctly at ~650 ms. I am now on v8 and all 4x VSAT links show incorrect latency information.

Bump… anyone?

I always assumed that this is observed Latency of traffic passing via the WAN in question that then gets pushed back up to IC2 for reporting purposes.

@Michael will know for sure. By the way, the best way to get quick answers about IC2 is by using the feedback button on the right when you’re logged in. That goes straight to the IC2 team.
