Check If Your Internet Is Working
Network Status is a real-time connection monitor that tells you at a glance whether your internet is working and how healthy it is. It shows your online or offline state instantly and measures the quality of your link with ping, jitter, and a clear quality rating.
Unlike a simple "am I online?" check, this tool goes deeper into connection stability — not just speed. That matters for video calls, gaming, and remote work, where a fast but unstable connection still feels laggy. It is built for remote workers, gamers, IT staff, and anyone troubleshooting a flaky line.
How to Check Your Connection
Read your connection status
The status indicator at the top updates automatically. A green Online pulse means you are connected; a red Offline state means there is no internet connection. It reacts the moment your link changes — no refresh needed.
Run a connection test
A quick test runs automatically when the page loads. Press Test Speed for a fuller test with larger data samples and more ping measurements. Watch the progress bar move through latency, download, and upload.
Read the results and rating
Download, upload, latency, and jitter appear in the metric cards. The Results tab shows an Excellent, Good, Fair, or Poor Quality Rating so you do not have to interpret raw numbers yourself.
Monitor live while you adjust
Flip the Live Monitor switch to keep testing continuously. It runs a new test 5 seconds after each one finishes, so you can see metrics change as you move the router or switch networks. It stops on its own after 15 minutes.
Features
Real-Time Connection Status
The indicator switches between Online and Offline the instant your connection changes, with a pulse animation and no manual refresh.
Accurate Diagnostics
Tests run on Cloudflare's global network for consistent measurements. A quick 2 MB sample loads fast; Test Speed uses a fuller 10 MB sample.
Ping & Jitter
See round-trip latency and jitter — the variation between pings — so you can judge stability, not just raw speed.
Quality Rating
An Excellent, Good, Fair, or Poor verdict combines speed and latency into a plain-language assessment of your connection.
Live Monitor Mode
Re-tests automatically 5 seconds after each result, so you can watch the effect of moving your router or switching WiFi. Auto-stops at 15 minutes.
Connection History & Trends
Recent tests are saved with timestamps and plotted on a mini trend chart, so you can track improvements or document issues for your ISP.
Server & ISP Information
The Results tab shows which Cloudflare location handled the test and your detected ISP, helping you tell local problems from routing ones.
Flexible Units
Toggle speeds between Mbps (ISP advertised) and MB/s (file transfer) with one click. Your choice is remembered for next time.
Copy Results
Copy your full status, speeds, and server details to the clipboard in one tap — handy for sharing with tech support or keeping records.
Frequently Asked Questions
How do I check if my internet is working?
Just open the page. The status indicator shows Online or Offline straight away, and a quick connection test runs automatically. For a deeper check of speed and stability, press Test Speed.
What does this test measure (ping, latency, jitter)?
Ping (latency) is the round-trip time for data to reach a server and return — lower is more responsive. Jitter is how much that ping varies between measurements; low jitter means a steady connection. The tool also measures download speed and estimates upload, then rolls everything into a quality rating.
What is a good ping or latency?
Under 50 ms is good for gaming and real-time apps, and 50–100 ms is fine for casual use. Over 100 ms can cause noticeable lag in competitive games. Stability matters too — a steady 80 ms often feels better than 40 ms with high jitter.
What is jitter and what value is good?
Jitter is the variation in your ping over time. High jitter causes choppy video calls and lag spikes even when your average ping looks fine. Under 30 ms is generally acceptable; the lower and steadier, the better.
Why does my connection show offline when I seem connected?
This usually means you have local network access but no internet reachability. Check whether other websites load. Common causes are DNS issues, router problems, or an ISP outage.
Why does upload show as "estimated"?
Browser security rules (CORS) prevent direct upload testing to external servers, so upload is calculated from your download speed using a typical upload-to-download ratio. For an exact upload figure, use your ISP's own tool or a dedicated app.
Why are my results different from other tools?
Results depend on the test server location, the measurement method, and current network conditions. This tool uses Cloudflare's worldwide network; other tools may connect to different servers or measure in different ways, so some variation is normal.
Is my data being collected?
Your test history and unit preference are stored only in your browser's local storage. Cloudflare processes the diagnostic requests to run the test, but this tool does not send any personal information or store your results on our servers. Clear your browser storage anytime to remove the saved history.
