But also worthy of recommendation IHMO is the Cloudflare one (speed.cloudflare.com). Main reason I say that is its one of the few that measures jitter (or at least openly exposes the measurement).

Or the cabling to the cloudfare server is worse than to other servers
I'm looking at the network tab, it seems like they send a ton of small requests instead of a large one... which might point in the direction of the problem.

Example: Rackspace Sydney (AS58683) has (likely paid) peering with AS7474, who has peering with German Deutsche Telekom (AS3320). Peering with DT is significantly more expensive than many others because they have a regional monopoly.
* Cloudflare is present at many regional Internet Exchanges and any good ISP connects to these, too. Some don't, however, like Deutsche Telekom.
Nice to see the tests are breakdown with more info when hovering or expanding them.
It does but it's hidden, you have to hit "Show more info" (once the main test has finished).
A bit stupid, but I'm sure some committee thought it was an awesome idea to do it that way.
Is it after the speed test is over?
Yeah, you have to let it run thorough first, then the button appears.
(At least on desktop, I can't remember what it does on mobile)
