Docker Outage History

Docker conducted scheduled authentication maintenance to rotate TLS certificates and update configuration for auth.docker.io and auth.docker.com. The work affected 4 components — Docker Desktop, Docker Hub Registry, Docker Authentication, and Docker Hub Web Services — with no service interruption expected; some users may have seen a one-time prompt to trust a new certificate. The maintenance window began at Dec 9, 2025 3:05 PM UTC and concluded at Dec 9, 2025 4:20 PM UTC.

During 9:10 AM UTC to 9:20 AM UTC, Docker experienced a brief outage impacting three components: Docker Scout, Docker Hardened Images, and Docker Hub Registry. Users attempting to access Hub and Registry saw increased HTTP 500 errors, with related tooling potentially failing or experiencing degraded functionality. The incident began with a status update noting elevated error rates on Hub and Registry and a subsequent investigation, and was resolved when the affected components returned to normal. The provider issued 2 status updates during the incident.

An outage affected Docker Hardened Images catalog and Docker Scout, causing partial disruption for users trying to access those features. The incident began at 7:35 PM UTC when Docker's status page moved from up to warn and cited disruption to the Hardened Images catalog and Docker Scout. The issue persisted for about 3 hours and 35 minutes, with the services returning to normal at 11:10 PM UTC. Docker issued 2 status updates during the incident, confirming the disruption and later restoring full functionality.

From 12:00 PM UTC, Docker Hub experienced degraded performance across Registry Push/Pull and related web services, while Testcontainers Cloud and Offload reported errors as Cloudflare's global network issues affected control plane operations. Docker Hub components were reported fully operational by 1:45 PM UTC, while Testcontainers Cloud remained degraded until 5:25 PM UTC. The Docker status page issued six official updates during the incident, documenting the degradation and subsequent recovery.

From 1:05 PM UTC to 2:00 PM UTC, Docker Hub Registry and Docker Authentication were under maintenance to rotate TLS certificates and update configuration for the auth endpoints (auth.docker.io and auth.docker.com). No service interruption was expected, though some users may have seen a one-time prompt to trust the new certificate. The maintenance concluded with both components returning to normal operation at 2:00 PM UTC, and the status page posted 2 updates during the incident.

An authentication provider issue caused login failures for Docker Hub for some customers. The Docker Authentication component entered a degraded state at 7:45 PM UTC and the problem persisted for about 55 minutes before the service returned to normal at 8:40 PM UTC. The Docker status page documented the incident with updates noting the login problems and eventual restoration. The issue appeared limited to a subset of users rather than a global outage, and the provider issued two status updates during the incident.

Docker Authentication login failures prevented most users from logging in to Docker accounts, causing a widespread authentication outage. The incident began on Nov 12, 2025 10:40 PM UTC and was resolved by Nov 13, 2025 3:00 AM UTC, lasting roughly 4 hours and 20 minutes. The official status page indicated the issue as a degraded authentication state affecting the Docker Authentication component. The incident included two official status updates as teams investigated and resolved the problem.

The Docker Hardened Images component experienced an outage from 2:00 PM UTC to 6:00 PM UTC UTC, preventing image pulls for new organizations created via DHI self serve free trials. This disruption impacted onboarding and any workflows that required pulling images for newly created orgs.

The Docker status page documented the incident as the Docker Hardened Images component moved from up to warn and back to up. The provider issued 2 status updates during the incident, and the outage lasted about 4 hours before service was restored.

Docker Authentication and Docker Hub Web Services experienced a brief outage starting on Nov 6, 2025 8:35 PM UTC, with some logins failing. The issue affected authentication and Docker Hub services, leading to login difficulties for a portion of users. The outage lasted approximately 4 hours and 20 minutes and the services were returned to normal by Nov 7, 2025 12:55 AM UTC.

During the incident, Docker issued two official updates, first noting investigation into failed logins and then confirming restoration of services as the issue was resolved.

During a scheduled maintenance window, Docker Hub Automated Builds were temporarily unavailable starting at Nov 5, 2025 2:00 PM UTC. The incident affected two components: Docker Hub Automated Builds and Docker Scout, with Autobuilds remaining impacted as the maintenance progressed. The status updated from maintenance to warn at Nov 5, 2025 3:20 PM UTC, then Docker Hub Automated Builds recovered by Nov 5, 2025 4:05 PM UTC and Docker Scout by Nov 5, 2025 5:00 PM UTC. The entire window lasted about 3 hours, from Nov 5, 2025 2:00 PM UTC to Nov 5, 2025 5:00 PM UTC. The provider issued four status updates over the incident.
