Repository mirroring
We mirror all non-archived GitHub repositories tagged with govuk to AWS CodeCommit (in the Tools environment, eu-west-2) every 2 hours using a ‘Mirror GitHub repositories’ Jenkins job. The job is configured in govuk-puppet and the govuk-repo-mirror repository.
The backups allow us to continue deploying if GitHub is unavailable. They also give us a private place to develop fixes for security vulnerabilities before they are deployed.
