Is there any page that gives some statistics of the Stratum # of pool servers?

I don’t seem to recall any page on the pool website, and I just browsed again to be sure.

It would be kind of cool if maybe like on the Zone pages it gives a list of how many active servers are of each stratum…

i.e.

Stratum 1: 123  
Stratum 2: 253  
Stratum 3: 35  
…

The Stratum data already exists as it shows it on an individual’s management page.

Neat, even though it’s 11 years old, I bet the distribution hasn’t changed much.

Not a site either, but there is a two-year-old study about the NTP infrastructure: [https://www.syssec.ruhr-uni-bochum.de/research/publications/NTP-Study/](https://www.syssec.ruhr-uni-bochum.de/research/publications/NTP-Study/) (the PDF link), on page 9 there is a table how it was in 2017 (and the data is available under the github link).
