Message:

Disable SSL 3.0

SSL 3.0 is only required by IE 6 on Windows XP, both of which are
unsupported.  Those users can upgrade to IE 8, switch to another
browser, and/or get a supported OS if they want to continue making SSL
connections to us.

By forcing downgrades from TLS 1.x to SSL 3.0, attackers could force
the negotiation of non-forward-secret ciphers.  It’s time to stop
letting IE 6 hold back security in current browsers.
