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.
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. 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.
