Let’s review: these packets travel from my location to Toronto to Chicago to New York to Montreal to Ottawa to Carleton University to the machine named Rideau. Final times in that last step: 52.879 ms, 50.997 ms, 49.468 ms.

I can see the building housing Rideau.carleton.ca through the window. It is down the street.

Christ.

    Ah, the wonders of Carleton computing.

    I wonder when they’re going to cut off my access.

    Are you trying to prevent the NSA from tracing your computing?

    Strangely enough, they were talking about exactly this sort of thing on Daily Planet today on Discovery Channel. You can probably catch it early tomorrow or very late tonight.

    It doesn’t help that one of the providers in this traceroute purposefully route traffic over links that are non-Canadian. It’s seen by them as a competitive differentiator, which shows just how little they get the whole concept of public networks.

    *sigh*
