On August 25th at 11am PT (Saturday), we’re performing major infrastructure upgrades to Docker Hub, Store and Cloud. We anticipate this upgrade will take between 15 and 45 minutes to perform.
We’re updating the database version these services are using. This allows us to pick up performance improvements that will result in a better user experience.
All services on Docker Hub, Store, and Cloud will be unavailable during the upgrade. This means you will not be able to pull or push images to Docker Hub, use the web UI for Hub, Store, and Cloud, or login to any web properties that uses hub.docker.com or id.docker.com for login (for example, support.docker.com and forums.docker.com).
