Speedtest only shows the Highest speed achieved Speedtest only shows the absolute maximum reached at any point during the test. It needs to show your average speed to be useful to any real degree at all. My test showed speeds between 30-40 except for the last second or two of the test - then it jumped to about 100. Speedtest reported my speed as 100. I watched the whole test and with an average of between 30-40, to report only the speed at the very end is not honest or accurate at all. Use Speedof.me - it does several tests and shows the average speed of all of them combined. Much more accurate and honest. I've tried both several times over a few weeks. The speeds reported are not even close. Speedtest.net always shows exaggerated much higher speeds than what I really get consistently.

Liers. Liers.. Every other reliable speedtest showed me 100/30 while yours shows me what im actually paying for... well I guess everyone can be bought. I'll make sure to spread the word about your scam :)

It's ironic... It's ironic, because every time I visit this site, the connection speed goes down for all users of my WiFi. This will of course mean the site shows my speed as slow, (which it, itself is causing). This means that I can't get any accuracy.

Speedtest.net isn't the problem Speedtest.net isn't the problem. The people who ring claiming to be from BT, use speedtest.net to get an idea of the speed you currently have, then they'll ask you to open another window on your browser, input some address and follow their instruction. That's where the real problem is. Don't type the address in. Hang up.

Something wrong here I have just spent 16 minutes with Speedtest (Jane Lewis and a very strong Indian accent) She claimed to be with Openreach, and advised me that I have a problem with the speed on my internet. and needed to log on to her website, I did this and she tried to get me to hit the consent box, I refused as it meant giving permission to send me junk mail. she got very abusive, accused me of wasting her time. I gave her a piece of my mind, asked for her supervisor, she then hung up on me. Proceed at your own risk.
