How this check works
The moment the page opens, it runs three checks. First it asks your device whether it's connected to a network at all. Then it sends a tiny request to two completely separate services, Google's public DNS (8.8.8.8) and Cloudflare's (1.1.1.1), and times the answers. They run on different networks owned by different companies, so if both answer, your internet connection is working. If neither answers, your connection really is down, even if your device shows full WiFi bars.
The website check goes one step further. It looks up the site's address, which tells you whether the domain exists at all and catches typos. Then it tries to reach the site from your browser. If the site answers, it's up and reachable from your connection. If it doesn't answer while Google and Cloudflare do, the problem is on that site's side or somewhere between you and it.
One honest limitation: a browser can see whether a site answered, but not what it answered. A site can be "up" and still show an error page or have a broken login. Some sites, especially ones behind strict bot protection, also reject checks like this even when they're working. The result tells you when that might be the case.
What the results mean
Your internet is working
Both services answered. If a particular website or app still isn't working, check it with the site checker. If the site is up too, the problem is usually the app itself, your browser (try a private window or clearing site data), your account, or a VPN or ad blocker getting in the way.
Connected to a network, but no internet
Your device is connected to WiFi or a cable, but nothing beyond the router is answering. This is the classic "connected, no internet" situation. Restart your modem and router, check your provider's status page or app for an outage in your area, and look at the lights on the modem. If you're on hotel, café or airport WiFi, open any website: you may need to accept a sign-in page first.
Your device is offline
The device itself says it has no network. Check that WiFi is turned on and connected to the right network, that airplane mode is off, or that the Ethernet cable is firmly plugged in at both ends.
Partly working
One service answered and the other didn't. That can be a brief glitch, a connection that's dropping in and out, or a network that blocks certain services, which is common on school and office networks. Run the check again. If results keep changing, your connection is unstable. The WiFi drop test will show how often it drops.
Quick fixes when your internet is down
- Restart the modem and router. Unplug both for 30 seconds, plug the modem in first, wait until its lights settle, then the router.
- Try another device. If your phone on the same WiFi works but your laptop doesn't, the laptop is the problem: toggle WiFi off and on, or restart it.
- Use a cable. If Ethernet works and WiFi doesn't, it's a WiFi problem, not your internet.
- Check for an outage. Your provider's app, status page or social accounts usually confirm area-wide outages.
- Turn off the VPN or any security software for a moment to rule it out.
Internet keeps going down?
If you find yourself on this page every few days, the problem is intermittent, and those are the hardest to get fixed, because by the time you call your provider everything works again. Leave the free 24/7 monitor running in a browser tab: it checks your connection every second and records every outage with its exact time and length. That gives you evidence instead of "it keeps dropping". Our guide on how to prove your ISP is unreliable shows how to use it, and is my internet working? covers more ways to check your connection.
Drops keep coming back? Record every outage with a timestamp so your provider can't dismiss it.

How do I know if my internet is down or just one website?
Check two or more unrelated services. If they all answer, your internet is working and the problem is with the specific website or app. This page does that automatically, then lets you check any website from your connection.
If this page loaded, can my internet be down?
If it loaded just now, you have at least some connection. But it may have loaded earlier or from your browser's cache, or your connection may be dropping on and off. The live check at the top tells you what's happening right now.
What should I do if my internet is down?
Check your WiFi or cable, restart the modem and router, check your provider's status page for an outage, and try another device. On public WiFi, open any website to trigger the sign-in page.
Is a website down for everyone or just me?
If the site answers here but doesn't work for you, the problem is likely your browser, app or account. If it doesn't answer while other sites work, use the share button to ask someone on a different network to check it.
Why does my internet keep going down?
Usually weak or congested WiFi, an overheating or faulty router, loose cables, or problems on your provider's line. Run the WiFi drop test to see whether it's your WiFi, and leave the 24/7 monitor running to log every outage.
