We've been running the current stable code base of Belay on public servers for almost a year. That phase of the project has come to the end of its life. We'll be turning down those servers on October 1st, 2012.
If you have need of the services we are currently running beyond October 1st, you can run your own copy of the code either locally, or on your own AppEngine application. Please contact me if you need any assistance.
