The main business is selling the data. You use Speedtest.net to troubleshoot your connection but metrics captured with the test alongside location data give telcos invaluable insights on where they should improve their networks. Telcos pay 6 figures annually for this data and we have a few hundreds of of those big MNOs globally. This market is pretty big. Accenture is in trouble with their main consulting business due to AI so acquiring data business is one of the smart strategies they can implement to stay relevant.
To all commenters who think they can code it over the weekend, yes you are right. I coded my first speed checker over the weekend in 2008 but it took me 18 years to grow the user base , figure out entreprise sales strategy and exit. Its not easy as it seems.
If you don’t get all of those parts right, you are going to end up measuring your own bandwidth rather than the client’s.
The website, and backend code for the test. 10% of the software work. Which is what everyone seems to think.
The code to managing the infrastructure, network connectivity, load balancing, and capacity planning is the 90% of the software part. But even then it is only 10% of the technical thing.
Getting all the ISP onboard to have your server in their network / exchange and to deal with you, takes more time and effort then all the software part. But even then it is only 10% of the project.
The remaining 90%? Non technical part for Sales and Marketing and getting user traction.
To put that into perspective, the website can be done in a weekend was only 0.01% of the work.
Whats even worst then your competitors can claim awards for the Fastest ISP and your marketing people are furious!
Some ISPs wanted us to pin to their servers in our app to have the best possible results (we refused) while others wanted us to use their servers because they offered 10G service and none of the other servers had that much throughout. So their true 10G line would be limited by the server, not the line.

Without it, it limits your ability to recover damages from infringement.
Downdetector in fact just seems to be a website catalog with essentially a guestbook and hit counter...
If you tell the “hey frankyspeeddetect.com isn’t doing my 500mbps” they’ll tell you to it’s an issue with that random website. ISPs and services reach out to Ookla to onboard with them because they have a network effect/mindshare of whatever you wanna call it
It happened enough times that I'm suspicious the ISP had some way to detect if you run a speedtest, and then prioritized traffic to that customer.
Fast is a one click solution to finding out your download speed from Netflix.
Latency doesn't matter, nor does upload.
That's why speedtest.net is a great purchase for Accenture. Of course Cloudflare's speed test is accurate: it's a test of how fast your connection is to their network. No more, no less. That their network doesn't have the same PoPs means it'll have different numbers than Ookla's test, your ISPs advertised numbers, Netflix's test, and any other speed test. But for people that don't see the Internet as a pile of different interconnected networks, the conclusion that a particular test is inaccurate is a win for Accenture.

that capilarity is not something you can achieve overnight.
I don't know whether it pings to italy even outside italy/eu

Fast.com would detect that, and you could bypass that nonsense by changing your DNS.
Downdetector wins because of SEO. Most people don't get there directly, they google for "is $x down" and then get sent to downdecetor. Which from my understanding works by simply showing you how many people came to their site with those search terms. They don't actually check the sites.
speedtest.net has been the first search result on Google for "speed test" for decades. Partly the boost of domain SEO and partly the boost of it being an effective exit node for searches for that term for that long.
(Nobody searches "ookla" and nobody is going to search your tier-3 .com)
I doubt they didn't collect all of that.
P.S. Now marry that huge dataset with services that Accenture provides, among others:
"In February 2025, Vice News spoke to a former Accenture employee under the condition of anonymity. His project on the WhatsApp team for Meta required him to sift through images and decide whether or not they depicted child sexual abuse, which he coped with "through a lot of substance abuse". The former employee claimed to have witnessed multiple missed opportunities to protect children, and alleged that one colleague had previously been arrested for possessing child abuse materials. In a statement, Accenture said they are "committed to helping companies keep their platforms safe through services such as content, advertising, and compliance reviews."¹
