What UpButler measured

Registry is answeringHTTP 401 · 300 ms

One request without credentials to registry-1.docker.io every two minutes, from eu-central (one location, not a global view). An answer (the expected "not authenticated") shows the edge, TLS and routing work. It does not prove that authenticated calls succeed. The probe is for Docker Hub as a whole, not for Docker Build Cloud specifically.

2026-07-130 of 1 days with an incidenttoday

Each bar is a day, coloured by the worst incident Docker Hub reported for Docker Build Cloud. It is their incident record, not a measurement of uptime.

No finished incidents on record yet since 2026-10-10. UpButler keeps what Docker Hub publishes for 90 days from the day it starts tracking a service.

Get alerted when Docker Build Cloud goes down

No account. One email when Docker Hub reports an incident that affects Docker Build Cloud, one when it is over. You confirm the address first, and every email has a one-click unsubscribe.

Or follow the RSS feed. On UpButler? Add Docker Hub as a dependency to route it to Slack, Teams or a webhook.

Status badge

Show Docker Build Cloud's current status in a README or an internal wiki. It updates by itself.

Tell your outage from Docker Hub's

Declare that your project depends on Docker Build Cloud. When one of your monitors fails while Docker Hub has an incident that began around the same time, UpButler tags your incident "likely upstream" with their incident linked, says so in the alert and the AI report, and tells your on-call agent not to change code.

npx upbutler init finds the dependency from your env var names and packages. The catalog, dependencies and upstream-aware incidents are on every plan, including Free.

Questions

Is Docker Build Cloud down right now?
No. As of 2026-10-10 07:17 UTC, Docker Build Cloud is up. This page reads the status again every 2 minutes.
Where does this status come from?
From Docker Hub's own status page API at https://www.dockerstatus.com. UpButler reads it once for everyone (not once per visitor) every 2 minutes with conditional requests, and shows it unchanged: incident titles and component names are Docker Hub's words. Their page covers more than this page shows; it is narrowed to the parts that concern Docker Build Cloud.
What does UpButler's own Docker Hub check prove?
Every two minutes UpButler sends one request without credentials to the Docker Hub Registry (registry-1.docker.io) from eu-central. Any answer from the edge, usually HTTP 401, shows that DNS, TLS and routing work from there. It does not prove that authenticated requests succeed, and it is one location, not a global view. It is most useful when it fails before their status page changes; the page then says so.
Can I get an alert when Docker Build Cloud goes down?
Yes, without an account: enter your email on this page, confirm the link we send, and you get one email when Docker Hub reports an incident that affects Docker Build Cloud and one when it is over. There is also an RSS feed at https://upbutler.com/status/docker/feed.rss. Teams on UpButler can route the same alert to Slack, Teams or a webhook.
How can my agent or app check Docker Build Cloud status?
Fetch https://upbutler.com/status/docker/build-cloud/status.agent.json: a small JSON document with a verdict (proceed, retry, fallback or pause) and retryAfterSec. No key is needed. The same answer is an MCP tool, upstream_status {"service":"docker","component":"build-cloud"}, on https://upbutler.com/mcp/public.
How do I know whether an outage is mine or Docker Hub's?
Add "docker" to the dependencies of your UpButler workspace. When one of your monitors fails while Docker Hub has an incident that began around the same time, your incident is tagged "likely upstream" with their incident linked, and your on-call agent is told not to change code.
