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
| 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.
