Outbound links from Twitter (t.co) breaking

This is what happens when you rely on link shorteners. You risk breaking the internet.

Link shorteners have the potential to dramatically reduce the robustness of the internet. A single failure point can break a lot of stuff. To my knowledge Twitter justifies their link shorteners with a security argument: they can easily prevent outbound clicks to suspicious sites. Although there is certainly value there, I'm skeptical. I bet it's more a matter of getting data on the kind of outbound traffic they're driving.
