Is Docker Hub down?

Live status for hub.docker.com from Drumbeats' own probes, with 8-day uptime, outage history and Docker Hub's official status feed.

Docker Hub is up

Last checked from Europe at (HTTP 401 in 437 ms).

This checks the Docker Hub registry API that `docker pull` uses. An unauthenticated request is answered with HTTP 401, which proves the registry is serving.

Last check: from Europe · 437 ms · HTTP 401. Refreshes every 5 minutes.

What we check: GET https://registry-1.docker.io/v2/ every 5 minutes, expecting HTTP 401. A failure is only reported after a second region and a 30-second re-check agree.

Uptime is (successful checks ÷ all counted checks) over our own scheduled checks from Europe. Downtime is sample-derived at the same 5-minute resolution: every confirmed failed check counts as 5 minutes of downtime, except isolated blips, which count against uptime but not against downtime or the incident count. Blocked or unconfirmed checks are excluded rather than guessed.

Amber line: median (p50) of successful checks per hour (per day on the 30-day view). Thin line: p95. Measured from Europe; a single vantage point, so treat the absolute numbers as relative.

Outage history from our checks

A blip is a single confirmed failed check with successful checks either side; it appears here but is excluded from the incident count and the downtime figure above (it still counts against the uptime percentage). Durations are quantised to our 5-minute check interval, so they usually read slightly longer than the vendor's own figures.

Official status from Docker Hub

Source: www.dockerstatus.com, refreshed every 10 minutes. These entries are Docker Hub's own reports, not our findings. The gap between our probes failing and the vendor acknowledging it is usually the moment you are searching.

It says up, but you still can't reach Docker Hub?

A global check passing and your request failing are not contradictory. Work outward from your machine:

  1. Try another network. Switch to mobile data or a phone hotspot. If it works there, the problem is your office/home network, VPN or corporate proxy, not Docker Hub.
  2. Disconnect your VPN. Corporate and consumer VPNs exit from IP ranges that get rate-limited or blocked by bot protection; Docker Hub may be refusing that exit node specifically.
  3. Flush your DNS cache (ipconfig /flushdns on Windows, sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder on macOS, resolvectl flush-caches on systemd Linux) or point your resolver at 1.1.1.1 / 8.8.8.8 temporarily.
  4. Check your clock. TLS handshakes fail with confusing errors when the system time is minutes off.
  5. Check the region. Our probes run from Europe and US East. A CDN or regional edge failure elsewhere can affect you and not us. Try our website down checker against the exact URL you are using.
  6. Check whether it's your account, not the service. API keys expiring, quota limits and suspended workspaces produce 401/403/429 responses that look like outages from inside an app.

Frequently asked questions

Is Docker Hub down right now?

Docker Hub is up. Last checked from Europe at 09:28 UTC (HTTP 401 in 437 ms). This verdict comes from Drumbeats' own automated checks, run every 5 minutes from Europe and confirmed from US East before any failure is reported.

What exactly does Drumbeats check for Docker Hub?

We send a GET request to https://registry-1.docker.io/v2/ and expect HTTP 401. This checks the Docker Hub registry API that `docker pull` uses. An unauthenticated request is answered with HTTP 401, which proves the registry is serving.

Why do your outage durations differ from Docker Hub's own status page?

We sample every 5 minutes, so our durations are quantised to 5-minute steps and the shortest outage we can observe is one check interval. Docker Hub's own numbers come from internal monitoring with far finer resolution, and vendors often start the clock when they acknowledge an incident rather than when it began. Both views are shown on this page, clearly separated.

Is this page affiliated with Docker Hub?

No. Drumbeats is not affiliated with, endorsed by or a partner of Docker Hub. This page reflects independent automated checks from our own infrastructure, plus incidents Docker Hub publishes on its own status page, shown separately and linked to the source.

How checks, confirmation, blips and uptime work is explained once on the hub page.
