How to push to Heroku without putting the app down

Just wondering how everyone pushes updates to their production server on Heroku, without bringing the app down for a few couple of seconds?



Pushing to Heroku (especially using something like Unicorn), takes a while for the web app to load. Especially when there are end-users trying to access the site. They end up with 503 pages.It takes up to 30 secs to a minute for Unicorn processes to load.
