Users may have experienced authentication failures when using GitHub Apps, including failures in Git operations and API calls using app installation tokens.\n\nThe issue was caused by an issue in a caching proxy component and was remediated by rolling back that component to a previous version. We are taking steps to improve monitoring for cache miss anomalies to ensure that token authentication remains functional during infrastructure changes and reviewing our protocol for testing and when we upgrade third-party dependencies.",
