It's pretty trivial if know where all the construction projects on your path are... How so? Setup OTDR traces and watch them?
When you lose link on every pair in a bundle, but don't lose any of the buildings you're serving via diverse paths, you have a pretty good idea what happened. Knowing which of the three construction projects on that path is likely to be digging a trench is a facilities issue.
Right. So why the "near instant" response time. If it's a diverse path, one would imagine that they could respond in a few hours or a day and not have any impact. The fact that they are so closely monitoring the construction and wanting to fix it that fast seems a bit over the top for redundant systems.
I've seen this happen on a university campus several times. no black helicopters were involved. Care to expand on the methodology used? A campus network is a lot different then a major metro area.
Given the location the guys in the blacks suvs likely have at least situational awareness of all of the contruction projects in their immediate vicinity.
One would hope. Though given the archaic nature of many govt systems, that could involve a lot of manual paper pulling... or are the bid/reward/permit systems all automated on the east coast? :) they don't have to monitor everyone's cable, just
their own and near instantaneous response implies proximity so it may well be more akin to a campus network.
True.
