Health checks are the only reason I’ve used 204 no content responses, so there’s that too.

Wait there’s nano? I’ve been using ed. /jk

Yeah those are some good points, I guess I’m just spoilt with native IPv6.

Oh okay, IMO IPv6 tunnels are worse than just disabling it, because it’s basically just a proxy with IPv6, and since there’s no encryption (at this layer) both your ISP and now the tunnel could collect your data, as well as added latency.

But I guess it’s okay for experimentation or if you actually require IPv6 for something.

http://google.com/ works fine for me, tested in Firefox and with curl -6. So it could actually be your side that is broken, although it is probably your ISP’s.
