Website speed test
Measure how fast any public website responds: DNS, connect, TLS, time to first byte, and document download, graded against a published rubric. Then test your own connection to separate "their server is slow" from "my internet is slow".
Free allowance: 5 tests a day, 25 with a free account, unmetered on Pro. Resets at midnight UTC.
Your connection to us
This panel runs in your browser and measures the path between your device and our edge, latency, jitter, and a rough download estimate. It cannot measure your path to any other site, browsers don't allow that, so use it as the "is it me" half of the diagnosis: if the site's server tests fast here but everything feels slow, your connection is the suspect.
The download number is an estimate from a single 4 MB burst, enough to tell "broadband fine" from "something is wrong", not a substitute for a full bandwidth test. Nothing about your connection is stored.
How we grade
Letters come from fixed thresholds, printed here so you can audit any grade we hand out.
| Grade | Time to first byte | Document transfer size | Redirect hops | Compression |
|---|---|---|---|---|
| A | ≤ 200 ms | ≤ 100 KB | 0 | brotli (or non-text) |
| B | ≤ 400 ms | ≤ 300 KB | 1 | gzip / deflate |
| C | ≤ 800 ms | ≤ 1 MB | 2 | - |
| D | ≤ 1500 ms | ≤ 3 MB | 3+ | - |
| F | worse | worse | - | uncompressed text |
Overall letter = weighted average (first byte counts double), nudged up a third of a grade when the host speaks HTTP/2 and down when it doesn't.
Game servers
Browsers can't ping game servers directly, so we don't pretend yours can. What we can show honestly: the latency our probes measure to every Minecraft server we track, refreshed every 5 minutes.
