You are missing ~70% of the tools functionality.

Did anyone claim it to be equivalent? I said it was more useful. Just a tip.

It's okay to be wrong.

All kinds of undocumented findings will occur in a closed source software. And this one is not even the most shocking.

I don't see any explanation of what the results mean. There is no man page; the help is just a list of options.

Personally I found it interesting that: * TFTP server [1] * PF Firewall [2] * pbcopy & pbpaste [3] are built-in in MacOS.

Pbcopy/pbpaste are huge productivity boosters for me

Pb stands for pasteboard and not for lead. :D

It’s an unreliable tool worldwide because (I assume) it uses Apple’s servers/CDNs, which do not reliably max out my bandwidth (400MB/s in France). Verify the results with another tool if you don’t live in the US.

This is a little weird for me:

Using Cloudflare's 1.1.1.1:

  ~> curl -s --doh-url https://cloudflare-dns.com/dns-query https://mensura.cdn-apple.com/api/v1/gm/config | jq -r .test_endpoint
  sgsin3-edge-bx-008.aaplimg.com
  PING sgsin3-edge-bx-008.b.aaplimg.com (17.253.61.15) 56(84) bytes of data.
  64 bytes from sgsin3-edge-bx-008.b.aaplimg.com (17.253.61.15): icmp_seq=1 ttl=52 time=74.2 ms

If I use 8.8.8.8:

  ~> curl -s --doh-url https://dns.google/dns-query https://mensura.cdn-apple.com/api/v1/gm/config | jq -r .test_endpoint
  hkhkg1-edge-bx-007.aaplimg.com
  ~> ping hkhkg1-edge-bx-007.aaplimg.com
  PING hkhkg1-edge-bx-007.aaplimg.com (17.253.85.13) 56(84) bytes of data.
  64 bytes from hkhkg1-edge-bx-007.aaplimg.com (17.253.85.13): icmp_seq=1 ttl=54 time=107 ms

Seems like I'm two different PoPs depending on which DNS I'm using.

From the article:

Apple's test_endpoint changes on each request, selecting a different nearby server to reduce latency and distributing their server load.

I have a shell alias so I can just type pb to do pbpaste|pbcopy - easiest way I’ve found to strip formatting and get plain text.
