The El Capitan public beta is now available from the Apple Beta Software Program.
Test-drive it and let us know what you think.

Also note that this particular release is also likely to further increase IPv6 traffic loads
once out in the mainstream, as it includes some significant changes to Apple’s “Happy
Eyeballs” implementation…   (see attached)   Current growth in IPv6 traffic doesn’t
necessarily include significant iPhone participation, but this will change shortly.

Hi everyone,

Today Apple released the first public seeds of iOS 9 and OS X El Capitan.
These seeds (and the third developer seeds released yesterday) include an improved version of Happy Eyeballs.

Based on our testing, this makes our Happy Eyeballs implementation go from roughly 50/50 IPv4/IPv6 in iOS 8 and Yosemite
to ~99% IPv6 in iOS 9 and El Capitan betas.
