Most of this is snakeoil. Why did you spend time on this article?
If youre too dumb to understand regions in Aus are going to be slower than your own NA backyard, youre not going to be subscribed to techspot or any tech site in the first place! Who is this article for? And if you are on an Aus server while in NA while subbed to a tech site, you probably have a very good reason. Whats the point of this? Youre trying to sell sand to the ocean.
Aint no one going to do any of that other crap either. Change DNS? Really??? Run ethernet to my laptop while trying to game comfortably on the couch or in bed for 5% (max!, this isnt 2005 anymore) ping gain? Oh hell no.
if you want faster ping (not the same as 'faster internet' where people associate download speed), then either get optical, move to eu, or hope to be chosen by StarLink.
