Did you know terraform registries mostly just return redirects to GitHub? GitHub is cracking down on unauthenticated requests as it tries to stabilize the platform. Using GitHub as a registry is less and less reliable. It's also one of the reasons homebrew moved to OCI. This is why Atmos supports a pass though Terraform Registry & Provider proxy so all requests are cached locally in your XDG cache folder. Combine that with the GitHub artifact cache, you can speed up your terraform runs in CI. Oh, and did you know atmos also supports pulling your modules from OCI container registries like the GitHub container registry? When you pull from container registries it's blazingly fast compared to git. github.com/hashicorp/terraform/issues/39130 github.com/orgs/community/discussions/206581#… Automatically retry transient errors with atmos: atmos.tools/changelog/terraform-component-retry Enable the registry cache: atmos.tools/changelog/terraform-registry-cache OCI vendoring atmos.tools/cli/commands/vendor/pull#…
