Thanks for checking out the recording! I'm glad that you learned something new! As time passes, you will meet more Hive witnesses, and if you attend some Hive meetups, you will get another dimension of HIVE in general.
What Gadrian said makes sense, but it's a bit techy to find the real location of the machine that runs the Witness node... I know that many are in Finland, with Privex, but there are others all around the world... If the person is in one place, it doesn't mean that the machine is in the same country...
I was thinking more about the continents, Australia, Asia, America, Africa. I believe that the Hive witness from, for example, Australia has his node in Australia.. But again, anything is possible🙂
Some do that... For example, I know that @forykw is running his @atexoras.witness Hive node from New Zealand...
