About Cloudflare DNS (1.1.1.1) outages
A public resolver outage is the most convincing impersonation of a total internet failure there is. Nothing resolves, every browser shows a DNS error, and the connection itself is perfectly fine. Because 1.1.1.1 is configured on a very large number of home routers and devices, an incident here produces a sudden flood of unrelated "everything is down" reports.
The diagnostic takes seconds: If a site loads by IP address but not by name, or if switching a device to a different resolver fixes it immediately, the resolver was the problem. Cloudflare's resolver has had genuine global outages, most notably a route leak in July 2024 that made the service unreachable for a portion of the internet. Status appears on the Cloudflare status page, and the resolver's own health can be checked independently at 1.1.1.1/help.
What to do if Cloudflare DNS (1.1.1.1) is not working for you
Is it them or you?
Our last check reached one.one.one.one normally, from a different network, resolver and route than yours. If it is broken for you, the fault is most likely local or too narrow for a single probe to see. Run the check again now to confirm.
The first thing worth trying
Notice the pattern before you troubleshoot. Three unrelated sites failing together is not three coincidences. Stop checking your own equipment.
How cloud & infrastructure services typically fail
Many unrelated services fail at once, in the same minutes, for the same people. Errors are inconsistent - some sites time out, others return a gateway error, others load partially - because each one fails at whatever layer it depended on. The rest of the steps, and why this category breaks the way it does, are on our cloud & infrastructure status page, with more background in how a single provider takes out half the web.
