This morning the jabber.org admin team installed a new build of M-Link provided by Isode. This build addresses the major issues we’ve had over the last month or so.
First, communication between Google Talk and jabber.org appears to be fixed. We can’t promise that you’ll never experience any difficulties chatting with your Google Talk friends, but the previous problem (lagged and in some cases lost messages) has been solved.
Second, the old legacy SSL port 5223 is working again, enabling you to connect using most older clients (e.g., iChat on Tiger) as well as various “crippled” clients that still don’t support STARTTLS on port 5222 (e.g., mobile clients like QIP and SIM). We will continue to encourage developers of those clients to add STARTTLS support and we reserve the right to turn off port 5223 at some point in the future, but we probably won’t do so until platforms like OS X Tiger and KDE 3 have been end-of-lifed.
