Dear Hector,
I left the instance up all day yesterday. I hit it and hammered it at the same time from 2 different computers. Once I restarted it at the beginning it did stay up.
I shut it down late last night and fired it back up this morning. After about 10 minutes I went to the other computer and it errored. I tried it again, shortly after that and it was up. So I'm not sure that it will continue to be stable but for now, it's doing what it was intended to do.
thanks.
