CERN's Jabber server was created in 2009 in order to fulfil some use cases that other collaborative tools couldn't address. Its close integration with Indico meant that users could conduct their meetings over a chat session, or just complement their videoconferences with textual information.

Fast-forward to 2016 and conferencing tools such as Vidyo and Skype provide their own chat systems. Other services (such as Mattermost) have meanwhile been put in place to provide the same kind of functionality we were aiming for at the beginning. They do it in a more user-friendly way than even modern XMPP clients.

This is why the Jabber service will be discontinued from the 19th of September 2016 on, in favour of the options above. Indico integration will consequently switched off. You are encouraged to download any logs you want to preserve using the "Logs" button next to your room name ("Chat rooms" section).

Thank you for your understanding and hope to see you on Mattermost!
