Why is the speed measured by speedtest.com and yandex.ru/internet three times different?

Question

Computer networks

Answer 1

Because in one case, the data goes straight through the peering, and in the other - through someone in the middle. And this is just one of the possible reasons.

Answer 2

The paths of the package are inscrutable, poke other servers on the speedtest, you will gain a dozen more different speeds. No one guarantees you speed, unless, of course, you buy a dedicated channel for an overdocher (and here, anyway, no one guarantees because the fuck knows where you are going to drive traffic there)

Answer 3

The fact is that the speedtest most likely uses the server of your provider when measuring speed - that is, it measures the channel provided to you by your provider. But when using the Yandex service, you most likely communicate with it through third-party networks, which is why the speed is less.
