The document outlines the CA/Browser Forum's phases of deprecating and revoking certificates for internal domain names, including commonly used TLDs like .local and .private. It began in 2009 by proposing to expand reserved names, launched a public review of requirements in 2011, made the requirements effective in 2012 by requiring CAs to notify customers of the change, and set revocation dates between 2015-2016. It also discusses the forum's rules for certificates containing new gTLDs once they are approved.
