This article only applies for users that have a plan which allows Zero Downtime Deployment feature. For more information check our pricing page.
Zero Downtime Deployment allows you to deploy your website without any downtime. You don't have to worry a second about your website going down for a second.
Ploi will take a copy of your website into another folder inside the /home/ploi directory. Then it will run the deploy script inside that newly created folder. After all the processes are done it will update the symlink to your new deployed and ready folder.
Ploi keeps track of 2 older versions of your website (which later will be customize-able and rollback-able).
