TL;DR: Apps on Meteor’s free hosting tier that have not had any activity in the last 6 months will be deleted on December 7. You can prevent an app from being deleted by simply accessing it from your browser.
As part of our preparation to transition the free hosting from its existing platform to the Galaxy free tier, we want to clean up abandoned apps while leaving active apps alone. As a first cut at this, on December 7 we will delete any app that hasn’t seen any activity at all in the last 6 months. This policy will also apply to future apps, so you should expect that any app that not accessed for a 6 month period may be removed.
If you have an app that is important to you, the only thing you need to do to keep it alive is access it from your browser. If we see any activity on that site, we’ll leave it alone. Deploying a site also counts as access. If your app gets deleted, you can of course redeploy from your codebase, but any data in your database will be permanently lost.
Thanks for your help as we upgrade our infrastructure.
