I semi-regularly come across what I believe to be messed up BGP routes (doing support for global companies trying to reach specific webhosts) and yet I'm still just absolutely stumped on find any way to report the issues. I imagine that's to reduce support load on the network teams running all of this, but some kind of check would be helpful.
