The Org server is now up. It is running Pre-release version 1.9.5. You must update your client software to be able to connect. All you need to do is download the new minecraft.jar file and replace your old file with it. The default location for this file is:

Win XP: C:\Users\USERNAME\Application Data\.minecraft\bin\
Win 7: C:\USERS\USERNAME\AppData\Roaming\.minecraft\bin\

I mainly installed this update to fix the experience orb bug that's forced me to do manual resets on the server a couple times now. However, it also adds a ton of other stuff, including breeding, potions, enchanting, repair, etc. You can read all the additions in the various pre-release versions here.
