H7. Keep your app running

What this page helps you do​

Think beyond the first deploy and keep the app stable after launch.

Why it matters​

Many apps go online once and then fail the first time traffic, a reboot, or a bad update hits.

You should already have​

  • a deployed app

Skip this page if​

  • you are still setting up the first deployment

What to do​

  • know how the app restarts
  • know where logs live
  • add uptime checks
  • have a rollback path

Assume something will fail and prepare the boring recovery steps ahead of time.

Common mistakes​

  • only testing a fresh deploy, never a restart
  • not knowing whether the app starts automatically
  • treating uptime checks as optional

Next step​

Go to R5. Uptime monitoring.

TODO for contributors: add a “first week after launch” survival checklist.
