Is Docker Hub down?

The status at the top of this page comes from Hyperping checks of Docker Hub, run every minute and refreshed on the page every 60 seconds. Green means the latest checks succeeded; red means they are failing, confirmed from several regions.

We monitor 4 Docker Hub services every minute, in turn from Virginia, Frankfurt and Singapore: Registry (registry-1.docker.io, up on a 401 response), Registry auth (auth.docker.io, up on a successful response), Hub API (hub.docker.com, up on a successful response) and Website (hub.docker.com, up on a successful response). When a check fails, other regions check again before that service counts as down. Docker Hub counts as down when all of them are, and as partly down when only some are. We check what docker pull needs, the registry and its token service, plus the Docker Hub API and website. Even an anonymous pull asks for a token first, so pulls can fail while the registry itself answers.

An outage can be partial: one feature, one app, one country or one internet provider, and our checks see Docker Hub from data centers. Try another network such as mobile data, update or restart the app, and check the official status page for an incident on one feature.

Yes, dockerstatus.com. Docker Hub's team updates it by hand, so it can lag behind the start of an outage; our checks run every minute whatever it says.

Yes. Create a free Hyperping account and add registry-1.docker.io as a monitor: you are alerted by email, Slack or your other channels within a minute of a failure. The free plan includes 20 monitors, enough for your own site and the services it depends on.
