Downtime: 2014-05-10, 9:00 due to server upgrade April 29, 2014, 6:31 p.m. by mati

On May 10, 2014, we will be replacing our current Ubuntu 12.04 operating system installation with Debian. We have become more and more disatisfied with Ubuntu as a server operating system and are slowly switching all our servers. At the same time, we will also use the opportunity to do a major ejabberd upgrade. The new version has a different configuration format, so the switch is not as straightforward as usual. ... read more

How-To: Good TLS encryption Sept. 21, 2013, 2:33 p.m. by mati

Recently, Thijs Alkemade published a three-part blog post on "The State of TLS security on XMPP". Part 1 covers the quality of TLS encryption on client-to-server (c2s) connections, while part 2 covers server-to-server (s2s) connections (and part 3 covers clients, not of interest in this article). Thijs also graded encryption quality, and as it turns out, jabber.at was in the top-spot in encryption quality. This may give us a reason to celebrate, but it does draw a sad picture of the quality of encryption on the Jabber/XMPP network. ... read more
