"Happy Eyeballs" (aka Fast Fallback) was created and named by Dan Wing and Andrew Yourtchenko of Cisco. And yes, "Happy eyeballs" is the official name (named because of how happy the eyes of the users will be when they see how fast their IPv6 connection falls back to an IPv4 connection when connecting to a host that does not support IPv6).

- p1mrx 11y agoHappy Eyeballs is primarily designed let users with broken networks continue connecting to dual-stack web servers. In some cases, it also covers up brokenness on the server end (e.g. publishing AAAA records to nowhere), but that's arguably more of a bug than a feature. Back in 2011, content providers were terrified of enabling IPv6, because the data showed that ~0.1% of users would drop off the map due to broken networks. Happy Eyeballs helped to break the logjam.
