My miners seem to be running smoothly on this pool.  None of them have fallen over to another pool in the last 2 days. (which I believe was due to unscheduled maintenance)

The vardiff ports helped me add more hash seems my issues is when using port 3333 so maybe that one needs work. other ports are working great.

So this tells me the issues are on the front end (which I am seeing too).  I am sure these issues will be ironed out.  All new pools go through these learning curves, I'm sure.
