What this tool does not do / Limits
This reports only what this browser says about its own connection, plus timing to the current origin. It does not test any other site, and it is not a full internet speed test.
Frequently asked questions
Does this test other websites?
No. Timing is measured to the current origin only, and no other site is tested.
What if it says offline?
That is the browser report, not a diagnosis. Check your device connection and try again.
