IOW: when my network fails "No route to host", I want to know who failed and why. Not just "hey, start the route tool on your production sever which you don't have access to, to get to know who slipped"

Yeah well, since you other people understand everything why don't you start developing your damn software yourselves as you please?

I used to understand networking in decent detail, but now many years later I've forgotten most of it.
