We have been measuring and tracing Zoom traffic from the various client apps for the last couple of weeks.
One weird thing. It appears Zoom uses SCO Cloud [1] and HunTel Engineering Nebraska [2] to form sort of their own IPX? I have been a cloud architect for the last decade and haven't seen anything like this. The costs must be enormous if we are measuring correctly (no guarantee).
SCO Cloud though is quite the character. Apparently they are part of some group that has been trying to sue the Linux kernel for the last 20 years, until the case was put to rest in 2017 I think [3].
