Telegraph measures your connection by transferring real data to and from a public test server — nothing about your device or browsing is collected or stored. Results can vary with Wi-Fi conditions, other devices on your network, and the test server's own load, so run it a couple of times for a reliable read.
About Telegraph
Telegraph runs a real network speed test — download, upload, and latency — directly from your browser, with no app to install and no account required. It reports results the same way most speed test sites do: megabits per second (Mbps) for throughput, milliseconds (ms) for latency.
Features
- Live-updating gauge while each phase runs
- Real download and upload throughput, not an estimate
- Ping and jitter measured over multiple samples
- Adaptive test size — short for slow lines, thorough for fast ones
- Shows your current public IP address
- No sign-up, no app, no tracking
How to use it
- Close other large downloads or streams for the most accurate reading.
- Click "Start Test."
- Watch the live gauge move through ping, download, then upload.
- Read your results in the three seals once the test finishes.
What the numbers mean
| Metric | What it tells you |
|---|---|
| Ping | Round-trip delay to the server — lower is better, especially for gaming or video calls |
| Jitter | How much that delay varies between requests — high jitter can cause choppy calls even with good speed |
| Download | How fast data comes to you — affects streaming, browsing, and downloads |
| Upload | How fast data goes from you — affects video calls, cloud backups, and live streaming |
Frequently asked questions
Why do my results differ from other speed test sites?
Every speed test uses its own server, test file sizes, and connection count, so small differences between tools are normal. Wi-Fi conditions and other devices using your network at the same time also affect results run to run.
Is my data uploaded or stored anywhere?
The test payloads (randomly generated data) are sent to a public test server purely to measure throughput — nothing about your device, browsing history, or identity is collected or stored by this tool.
Why did the test fail or show an error?
Ad blockers, privacy extensions, VPNs, or restrictive network firewalls can block the test server's requests. Try disabling extensions for this page or switching networks if the test consistently fails.
Does Wi-Fi affect the result?
Yes — a weak Wi-Fi signal, network congestion, or an older router can all reduce your measured speed well below what your internet plan provides. For the most accurate reading of your actual internet connection, test on a device wired directly to your router.
