Does seem to be on the uptick!
I have been using anycast at a small scale on mesh networks, for dns, primarily. Works.dns is udp
No. In my case, at least, I have been exhaustively testing dnsmasq + dnssec, which falls back to tcp a lot more often than it used to given all the headaches edns0 was causing, and cloudflare gleefully coming up with ever more innovative ways to dump weird stuff on the wire, like signing a domain with a control-c (\003.domain.com). Although 2.73 just (finally) shipped, I am still concerned about the tcp fallback in the anycast scenario. So I do kind of expect that there will be more tcp dns, and I think tcp dns is something android falls back to a lot, still.
