Which repositories are affected?
Starting December 8, 2026, GitHub will disable Dependabot alerts in most repositories with no activity during the previous year. Existing alerts will be archived rather than deleted and can be restored when alerts are re-enabled.
Pushing to any branch or tag, creating a repository, or enabling Dependabot alerts counts as activity. A new push automatically reactivates alerts; they can also be reactivated in repository settings.
Exceptions for enterprise policies
Alerts will remain enabled in repositories with a security configuration that requires Dependabot. Enterprise policies preventing repository administrators from changing the setting are also exempt.
The change applies to github.com plans and GitHub Enterprise Cloud with data residency, but not GitHub Enterprise Server. GitHub says it aims to protect alert service performance for actively developed repositories.
