Is Docker Hub Down?
No, Docker Hub is up. All systems operational.

What is Docker Hub?
Docker Hub is the world's largest public container image registry, operated by Docker, Inc. Developers and automated CI/CD pipelines use it to push, pull, and share container images. It serves as the default registry for the Docker CLI, meaning any docker pull command that does not specify a registry hostname resolves there automatically. Teams across software development, DevOps, and platform engineering depend on Docker Hub to distribute both official base images and private application images.
Signs Docker Hub is having problems
- docker pull commands hang indefinitely or return a connection timeout error without completing the image download.
- The Docker CLI returns an error such as "toomanyrequests" or "unauthorized" when pulling public images, which can indicate rate-limit enforcement issues or authentication service degradation.
- Pushes to Docker Hub repositories fail mid-upload or report a 500-level HTTP error from the registry API.
- Automated builds and webhooks in Docker Hub do not trigger after a repository push, even when the source code repository received the commit successfully.
Find out when your own services go down
You can check Docker Hub here — but a heartbeat monitor tells you the moment your API, website, or cron job stops responding, so you hear about your own downtime before your users do.
Frequently asked questions
How can I tell if Docker Hub is down?
The authoritative source is the official Docker status page at https://www.dockerstatus.com, which lists the current status of the registry, authentication, builds, and other components. You can also attempt a docker pull of a small public image such as docker pull hello-world from your local machine or CI environment to see whether the failure is reproducible. Checking community sites like the Docker Community Forums or developer discussion boards can confirm whether others are seeing the same issue.
Where is the official Docker Hub status page?
Docker maintains its official status page at https://www.dockerstatus.com. That page shows real-time and historical incident information for Docker Hub and related Docker services. Subscribing to updates there will notify you by email whenever Docker opens or resolves an incident.
Why does docker pull fail even when Docker Hub appears operational?
Docker Hub enforces anonymous and authenticated pull rate limits. Anonymous users on a shared IP address (common in CI environments using cloud-hosted runners) can exhaust the free-tier pull quota quickly. Authenticating with a Docker account raises that limit, and a paid subscription removes it entirely. If you are authenticated and still seeing failures, check whether Docker Hub's authentication service specifically is reporting degradation on the status page, as that component can have issues independent of the registry itself.
Can I get alerted automatically when my own services experience downtime?
The Docker Hub status page covers Docker's infrastructure, but it does not monitor your own deployments. If you run services or scheduled jobs that depend on Docker Hub, you can set up a heartbeat monitor on CronJobPro to receive an alert the moment your pipeline stops reporting in, so you know about a downstream failure before your users do. CronJobPro is not affiliated with Docker or Docker Hub.
