Website Connection Checker
Is the site actually down, or is it just your device? Enter any website and this tool runs DNS and connection tests from your own device — repeated four times, because the faults that matter are usually intermittent. Everything runs in your browser; nothing you type reaches our servers.
How the Website Connection Checker Works
The tool runs four stages in order, and each one rules something out:
- Your internet — loads a small file from this site. If this fails, your device is offline and nothing else below means anything.
- DNS lookup — asks a public resolver which IP address the domain points to. This shows whether the domain exists and is configured.
- Connection test — tries to open the site from your device four times, and reports how many succeeded and how long each took.
- Your environment — records whether you are in a normal browser or an in-app WebView, plus your platform and connection type, because the same site can behave differently in each.
Reading the result
- DNS fails — the domain could not be resolved on your connection. Either it is misconfigured, or your network's DNS is not answering for it.
- DNS works but the connection fails — your device knows the address but cannot reach it. That points at filtering, a firewall, or a routing problem between you and the site.
- Some attempts pass, some fail — an intermittent fault. This is the one a single test always misses, and usually the hardest to get taken seriously without a number attached.
- Everything passes — the site is reachable from this device right now. If it still misbehaves, the problem is inside the page or the app, not the connection.
Privacy: the checks run from your browser straight to the site you typed. We never see the address, and no result is stored or transmitted to us.
Frequently Asked Questions
Is this website connection checker free?
Yes. It is completely free, needs no signup, and runs entirely in your browser. Nothing you type is sent to our servers.
How is this different from a 'is it down' website?
Most down-checkers test the site from THEIR server, which tells you nothing about your own connection. This tool runs the test from YOUR device and network, so it can tell the difference between a site that is genuinely down and a site that only fails for you.
Why does it try four times instead of once?
Connection faults are often intermittent. A site that fails one request in five will look perfectly healthy if you only test once. Four attempts turn an intermittent fault into a visible number, like 2/4.
What does it mean if DNS works but the connection fails?
It means your device found the site's address but could not open a connection to it. That usually points to blocking or filtering on your network, a firewall, or a routing problem between you and the site — not a fault with the site itself.
Can it check a site that is blocked on my network?
It can tell you THAT a site is unreachable from your device and at which stage it fails. It is a diagnostic tool, not a way around a block.
Why do results differ between my browser and an in-app browser?
Apps that show web pages use a system WebView, which does not always share the main browser's DNS settings. Modern browsers often use encrypted DNS by default while a WebView uses the network's DNS, so the same site can work in one and fail in the other on the same phone.
