FAQ The link test on the Performance page does not measure upload

[Silas Mariusz]

Symptoms

• After a link test, the result reads Upload not measured: …, and the reason says that the endpoint is likely rate-limiting this address (e.g. HTTP 429).
• The result shows no upload speed and proposes no upload limit.

Cause
The link test measures against a public speed test service on the internet. For the upload, it makes three runs of up to 10 seconds each over four connections and keeps the median. When the service refuses the requests, for example with HTTP 429 (too many requests), the answers come back at once with almost no data. The test does not read the HTTP status. It treats a median of 0.1 Mbit/s or less as no measurement and repeats the three runs once. If the upload is still that low, the test records it as not measured, with the reason. A measured download still counts: the result keeps its download figures and proposals.


Resolution

1. Read the reason in the result on Performance. With Advanced on, the How it was measured card also shows Upload as not measured. The reason text is in English in every language of the panel.
2. Run the link test again later: under What to test select Link and press Run test.
3. Until a test measures the upload, set the upload limit by hand. Click the Upload speed at the top of Quick access and set a limit below the upload speed of your internet plan.

Notice & Advise

• Upload speed of your plan does not replace a missing measurement. The proposals use it only together with a measured upload.
• When neither the download nor the upload is measured, the test ends as Failed.
