There might be some problems but it's great to know that Google system administrators (instead of me) are taking care of it. When I hosted my application on EC2 twice I almost lost all my files due to hardware problems. I had to spend all night preparing a new server, not funny. There are no servers to fail in App Engine, I love that!
