hi @whatplan
By default, two Machines deploy for availability. For the fly log shipper issue, you could try this solution: Fly Log Shipper Duplicate Logs on Apps v2 - #4 by charsleysa
Or you can scale down to one machine with fly scale count 1.
Your app should then stay at one machine when you deploy, but if you ever scale to zero then use fly deploy --ha=false to make sure you only get one Machine on deploy.
