Each bar of the first strip is one check, five minutes apart; each bar of the second is a day. Height is response time, red is a failed check, amber a timeout. Times are UTC, as of 2026-10-06 11:38 UTC.

In the last 24 hours Cloudflare passed 288 of 288 checks, 100%.

No outage since checks began on 30 Sep 2026.

A year of checks is kept; the year's figure appears here once there is a year of them.

Response time by location

Over the last 7 days, from the checks that passed: the time from the start of the request to the answer's headers, with the DNS lookup, the connection and TLS included.

What is checked

CDN, DNS, DDoS protection, Workers and a large part of the web's front doors. StatOSS itself sits behind it.

StatOSS sends GET https://api.cloudflare.com/client/v4/ips and counts the check as passed on status 200 within 10 seconds. The API endpoint that lists Cloudflare's IP ranges. It is public and needs no token, and it answers through the same API that dashboards, Terraform and wrangler use.

It checks Cloudflare's API. Sites behind Cloudflare go through its edge, which is a different path and can fail in one place while the API answers.

Cloudflare reports its own incidents at www.cloudflarestatus.com. The figures here are measured from outside and can differ from it in both directions.

How it is measured

  • One check every 5 minutes, from one location at a time in turn: Aarhus and Copenhagen in Denmark, Falkenstein in Germany, Ashburn in the USA, Singapore, and Sydney in Australia.
  • A check fails when no answer comes within 10 seconds, when the connection or TLS fails, or when the answer is not status 200.
  • A failed check is repeated at once from a second location, and counts only when that location fails too, or cannot answer within 20 seconds.
  • Two failed checks in a row make an outage, dated from the second, and the first check that passes ends it. A failure shorter than 10 minutes may not make one, and times are good to about 5 minutes.
  • Availability is the share of checks that passed. There are no maintenance windows: every check counts.

It is the same check a StatOSS status page runs for its owner, with the same rules; the docs on checks have the details.
