[why-el]

Hm, I thought Happy Eyeballs (HE) was mainly concerned with IPv6 issues and falling back to IPV4. I didn't think it was this RFC in which finally some words were said about round-robin specifically, but it looks like it was (from this article).

Is it true then that before HE, most round-robin implementations simply cycled and no one considered latency? That's a very surprising finding.
