Internet Health Test
Use the free test below to measure your connection right now. It adapts to your speed and finishes in under a minute.
How the measurement works
The ladder starts small enough that even a 5 Mbps connection finishes quickly, then doubles the payload up to 100 MB so multi-gigabit fiber still gets a long enough transfer to converge.
Because the download is split into several measured passes, a single slow moment or network hiccup can be discarded instead of silently dragging the whole result down.
Because the method is adaptive, the transfer budget is a fraction of what fixed-size tests push through, without giving up accuracy.
What the numbers mean
Download is how fast data travels to you — it drives streaming, browsing and game downloads. Upload is the reverse and matters for backups, video calls and cloud work.
Latency is the round-trip time to our test server — small numbers are better for gaming and calls. Jitter measures the variation, and high jitter is what makes calls sound robotic even at low ping.
What affects your speed
Your measured speed can vary with the time of day, the device's Wi-Fi generation, and how many other people are using the connection.
No single test can represent every destination on the internet, but a path to a major edge network is the standard, neutral way to benchmark a connection.
A few final tips
Run the test a few times over a few days before drawing conclusions. One-off speeds are noisy; a median of several runs is a much more reliable picture of your connection.
Your data stays in your browser for the duration of the test; only a small, anonymous summary is saved afterward, and never the raw payload.
This test is free, requires no account, and never shows ads while it runs — the only goal of the measurement is to give you a trustworthy number as quickly as possible.
A few final tips
Internet Health Test is built to run on your connection in under a minute — press start, read the four numbers, and compare them with what your plan promises.
Speed test limitations
Wi-Fi adds its own variability. If your wired connection is much faster than your Wi-Fi, the bottleneck is your wireless link, not your ISP — and that is worth knowing before you call your provider.
Upload speeds can be throttled or capped separately from downloads on some plans, so a fast download with a slow upload is often the plan working as designed rather than a fault.
