Is My Internet Working?

How this test works

The page runs four checks in order. First, whether the browser says it is online. Second, whether this site's own Cloudflare page answers. Third, whether the name cloudflare.com resolves through a public DNS-over-HTTPS service. Fourth, whether a second Cloudflare address, reached over IPv4, answers. The last three each stop waiting after 5 seconds. It cannot see your router or modem.

How to read the result

The verdict is one of six: working, offline, no internet, site only, name lookup problem or partly working. All four checks passing gives Working, and none passing gives Offline. The browser being online while the other three fail gives No internet. Each verdict comes with a short list of things to try, most useful first.

What is typical

The page applies no typical times: each of the last three checks either passes or fails within 5 seconds. The checks reach Cloudflare services only, so a problem with one other website will not show. The advice for a name lookup problem and for a partial result starts with a VPN check.

What to do if it is bad

For Offline the list starts with the cable, then Wi-Fi, then mobile data, then the router, then the provider. For a name lookup problem it lists a VPN check, a change of DNS server and the router. For a partial result it lists a VPN check, a retry and the router.
