The XMPP Extensions Editor has received a proposal for a new XEP.
Title: Happy Eyeballs
Abstract:
When a server's IPv4 path and protocol are working, but the server's
IPv6 path and protocol are not working, a dual-stack application that
initiates a connect experiences significant connection delay compared
to an IPv4-only application. This is undesirable because it causes the
dual-stack initiating entity to have a worse user experience. This XEP
defines how IETF's 'Happy Eyeballs' algorithm requirements that reduce
this user-visible delay are applied to XMPP.

The Council will decide in the next two weeks whether to accept this
proposal as an official XEP.
