Enabling and scheduling maintenance mode

本文内容

Some standard maintenance procedures, such as upgrading your GitHub Enterprise Server instance or restoring backups, require the instance to be taken offline for normal use.

About maintenance mode

Some types of operations require that you take your GitHub Enterprise Server instance offline and put it into maintenance mode:

  • Upgrading to a new version of GitHub Enterprise Server
  • Increasing CPU, memory, or storage resources allocated to the virtual machine
  • Migrating data from one virtual machine to another
  • Restoring data from a GitHub Enterprise Server Backup Utilities snapshot
  • Troubleshooting certain types of critical application issues

We recommend that you schedule a maintenance window for at least 30 minutes in the future to give users time to prepare. When a maintenance window is scheduled, all users will see a banner when accessing the site.

When the instance is in maintenance mode, all normal HTTP and Git access is refused. Git fetch, clone, and push operations are also rejected with an error message indicating that the site is temporarily unavailable. In high availability configurations, Git replication will be paused. GitHub Actions jobs will not be executed. Visiting the site in a browser results in a maintenance page.
