The idea is to ascertain where an issue may lie. I understand the network will most likely heal its' self, however it's still nice to know where the issue lies.
I'd be careful how much value you put in real world geographical data and hence topology, vs network topology. As I think we're all aware, networks can be complicated beasties depending on which way you try and draw them.
I'm guessing customers connect directly to the erx's, thus if the erxcrash's and goes down, customer falling off that node will be effected.
Well yes, if a customer's single homed off of any device and it dies for some reason they'll lose service. But in most networks there are many more devices than just the routers, and I doubt you'll get anyone telling you their complete network layout.
The idea is a pretty map with colors indicating packet loss. Let's just see what happens when the next big network fault happens.
