XMPP Operators Begin Requiring Encryption, Google Still Not Allowing TLS 121

Via El Reg comes news that major XMPP (formerly known as Jabber, likely the only widely used distributed instant messaging protocol other than IRC) operators have all begun requiring encryption for client-to-server and server-to-server connections. Quoting the Prosidy developers: "Last year Peter Saint-Andre laid out a plan for strengthening the security of the XMPP network. The manifesto, to date signed by over 70 XMPP service operators and software developers, offered a rallying point for those interested in ensuring the security of XMPP for its users. Today is the date that the manifesto gave for the final 'flip of the switch': as of today many XMPP services will begin refusing unencrypted connections. If you run an XMPP service, we encourage you to do the same. On the wiki you can find instructions for all the popular XMPP server software. While XMPP is an open distributed network, obviously no single entity can 'mandate' encryption for the whole network — but as a group we are moving in the right direction." There is a handy tool to test your server. A result worth noting is Google's: they still do not support TLS for server-to-server connections, and their sudden dropping of TLS s2s connections a few years ago is likely the primary reason operators switched off mandatory TLS for s2s (I know that's why I did it). Although Google Hangouts offers no federation, GTalk still does, but it appears that the XMPP network-at-large will now cease to federate with Google voluntarily.

    So their lack of support for TLS with it is sort of a moot point. []

    Google is pretty well seated in the back pocket of the US government. Even if they were to endorse TLS it doesnt preclude them from silently forwarding all your conversations to the NSA.
    Voluntarily ceasing to federate is the logical conclusion to a software project run by people who care about their users, so nothing special here. However, voluntarily ablating yourself from Google, Facebook, Twitter, snapchat, and other "social" sites is probably a longterm goal to which we should all strive.
