Aside from some occasional weird routing, the network has worked really well. State has not been an issue for what we're doing (short-lived HTTP connections).
I'm just trying to see what the extent of my powers to control weird routing are. It's odd to see Comcast cold-potatoing connections to the wrong routes, sometimes on the other side of the continent ( https://gist.github.com/kyledrake/7a4cd36ea276ec3134b4a51a42a37f48). I'm wondering if there is a way to configure Bird to help steer these sorts of things a little better, even if it's on a case-by-case or region-by-region level. My apologies if these are all dumb questions. Again, not much anycast documentation out there (I'm planning to improve this later by putting together a web resource for people doing this). -Kyle
