GitHub public repositories have started verifying identities too: bot traffic has surged, and normal CI is suffering as a result.
GitHub announced on October 19 that it will temporarily add identity authentication for HTTPS download requests to some public repositories. Once the system detects abnormal traffic, code that could originally be cloned and fetched without logging in may suddenly require a token. CI builds and automated installation scripts that rely on anonymous downloads may also be interrupted as a result. Similar issues already appeared in September, when developers reported that CI servers repeatedly received `401` errors while pulling the public MariaDB repository, and even submodule updates could not be completed. GitHub explained that the platform is facing increasing bot traffic, and legitimate development requests may also be misjudged. This announcement further clarifies the scope of the temporary authentication measures and recommends that developers configure identity authentication for automated tasks to avoid relying on anonymous HTTPS pulls. Authenticated HTTPS and SSH operations are not affected by this restriction.
