ECMP doesn't work well on connection-based protocols, like TCP. Also, CloudFlare monitors processes and withdraws a route when a particular process dies, so that's why I mentioned that.

WRT to the second point, failure cases are not that simple. Edit: lets talk directly connected next hops, like a L2 domain. In this scenario what's the difference between "Anycast" and "ECMP"?
