This happened to me a few hours ago, I just waited about 2 hours tehn it worked fine.

A 503 error means that the server (session.minecraft.net) was unable to handle your request.

I believe that the server at that address handles authentications. Your Tekkit server is trying to authenticate you but cannot reach the authentication server.

This should only be a temporary problem.
