All 3 of the listed Wisconsin routers are small businesses. 2 are currently listed as being down, and have been for months now. However, their web pages are up, they probably just changed around their IP's or something, and never notified. I could see a core router at UW being a major measure of the internet, but not some small consulting company in a small town..
