The apps that I build (and use dokku to deploy - thank you josegonzalez, it's a great tool) are critical to their users. While ten, twenty, thirty seconds isn't much in the grand scheme of things, if it happens just as someone is doing an important update, it reduces trust in the software. If it happens a couple of times, they're going to report back to their boss that the system is unreliable and fails just when they need it most. And with international users, I can't be sure that I'm picking a time to do a deployment where no-one is going to be using it.
