How We Test and Review Our Guides
Last updated: November 2026
This page explains how our speed test measures your connection and how we research and maintain our guides, so you can judge the results and advice for yourself.
How the speed test works
The test runs entirely in your browser and measures your connection to Cloudflare's global speed test network, which has servers in hundreds of cities. Your browser connects to the nearest available server automatically.
| Measurement | How we measure it |
|---|---|
| Ping | 12 tiny requests to the test server. We drop the first one and report the median round-trip time. |
| Jitter | The average change in round-trip time between consecutive ping requests. |
| Download | Six parallel downloads for about 10 seconds, so fast plans are measured fully. We skip the first 1.5 seconds while the connection speeds up and report a stable figure from the samples that follow. |
| Upload | Four parallel uploads for about 8 seconds, reported the same way. |
| % of plan | Your download result divided by the plan speed you select. |
What the test can't tell you
- It measures the speed reaching the device you're using, so WiFi signal and older devices can lower the result.
- It measures to the nearest internet server, not to servers inside your provider's own network, so results can differ from your provider's own test by roughly 5–15%.
- One test is a snapshot. For a fair picture, test with a cable, at different times of day, and use the middle of three results.
How we research our guides
- Primary sources first. Steps for apps and equipment are checked against the provider's own support articles.
- Current plan information. Plan speeds are checked against current plan listings and dated on the page, because they change.
- Tested advice. Troubleshooting steps are tried on real home connections before we recommend them.
- Plain language. We explain technical terms in everyday words.
Updates and corrections
Every guide shows the date it was last reviewed. We review our main pages at least every three months and sooner when a provider changes its plans or app. If you spot an error, email [email protected] and we'll correct it promptly.
