You would be mistaken to think that a router's lack of responsiveness to your queries is indicative of forwarding capacity issues. To ask your question from the opposite point of view, are there any operators of large networks today that don't filter and police traffic destined for the control/management plane of their routers? Anticipating the answer to that question: I think it is only reasonable to limit the impact that random strangers can have on my network's stability. Your ability to traceroute is valuable, but not more valuable than my network's uptime. Cheers, -Benson
