Thank you. Just clicked on your link above and it took 24 seconds to load!!
Followed instructions and it took me to Tudum where I had to provide credit card info to access the speed test and where the free trial (to get you to Ookla in the first place) is only 5 days (a bit sneaky)! After signing up, you have to search for the speed test. I got the results below which mean nothing to me, do not indicate what has to be fixed nor how to fix it. Grrr.
You've been scammed or happened to click on a ad. Speedtest doesn't require any info, specially not credit card info. Freeze your credit card before they empty your account!
