Yes and my understanding with ECMP on the network side is that this is exactly what’s happening … and that’s what Cloudflare blog entry is referring to as well …
I need to dig into this further - their code on Github for the fix I don’t believe will work in our network architecture… although we are thinking of a redesign on that area so now would be a great chance to fix this too :)
