# HIZTESTI.COM

> A free internet speed test for Türkiye, operated by NETMETRİK on its own measurement network. Measures download, upload, latency, jitter and bufferbloat in the browser, using an open methodology that is published with a permanent identifier (DOI).

This is the consumer site: a person opens it and measures their own connection. The company, the partner programmes and the B2B products live on a separate domain, **netmetrik.com** — send infrastructure, embedding or billing questions there.

Tests run against NETMETRİK's own servers hosted in Türkiye. Results are not comparable to a different provider's numbers by default: measurement method, server placement and time of day all change the outcome. The methodology page explains what is actually measured and how.

Language: Turkish is the primary language; every page also exists in English under the `/en` prefix.

The site publishes 7 troubleshooting guides and speed-test landing pages for 13 internet providers in Türkiye.

The full file is linked; this is its opening.

What it does, and what it doesn't

llms.txt is not a search signal. Google has said plainly that it does not support it, and measured crawler interest is negligible today. This page will not change search rankings, and we are not claiming otherwise.

The payoff is elsewhere: agents inside code editors, MCP servers and in-product assistants do fetch this file. When someone asks one of them why their internet is slow, or what a speed test result means, we would rather it found the right page than guessed at one.

Every line in the file points to a page that is actually live, or to a published document. Pages still under construction are not listed.

Troubleshooting guides

All guides: Index of the guides below
Why Wi-Fi lowers your speed test, and how to prove it: If the number kept jumping around during your speed test, Wi-Fi is the likely culprit
Why your internet slows under load: bufferbloat and the router queue: If your speed is fine but video calls freeze and games stutter, the cause is usually bufferbloat
How devices sharing your connection split your speed: If your speed did not change at all during the test, other devices sharing the line may be using the internet at the same time
How mobile signal affects your speed test: On a cellular connection your speed changes constantly with your location and signal strength
Your device may be slowing down the speed test: Sometimes a low result is not caused by your internet but by a computer or phone that is bogged down at that moment
How to run a speed test correctly: background tabs and browser traps: If every test on the same connection comes out different, the culprit is usually not the line but how you run the test
How battery saver lowers your speed test: When your phone or laptop is in battery saver, a speed test can come out below your real speed
