There’s two main ways of doing geo-based load balancing:
- IP Any-casting - In this case, an IP address is “homed” in multiple spots and through the magic of IP routing, it arrives at the nearest location. This is exactly how 1.1.1.1 and 8.8.8.8 work. It works fine for stateless packets like DNS, however it has some risks for stateful traffic like HTTP.
- DNS based load balancing. A server receives a request for “google.com”, looks at the IP of the DNS server and/or the EDNS Client IP in the DNS query packet and returns an IP that’s near. The problem is that when you’re doing Wireguard, it goes phone -> pi-hole (source IP is some internal IP) -> the next hop (e.g. 1.1.1.1 or 8.8.8.8), which sees the packet is coming from your home/pi-hole’s public IP. Thus it gets confused and thinks you’re in a different location than you really are. Neither of these hops really knows your true location of your phone/mobile device.
Of course, this doesn’t matter for companies that only have one data center.
As a professional software dev, I worked with pretty much every OS daily. My personal computer was a Windows, my work laptop was a Mac, and I ran my code on Linux so I was familiar with the things I liked and disliked about each. I also ran my own set of server with my websites, mail servers, and various research projects to learn and grow.
Then I decided it was time to order a new laptop and I didn’t want to go to Windows 11 because I felt Microsoft was going too much into features I didn’t want like Ads, more tracking, pushing AI. Don’t get me wrong, I like AI, but it was too much about forcing me to use it to justify their stock valuations.
I also was working on reducing my usage of big tech, setting up self hosted services like pi-hole, Home Assistant, starting to work my own Mint alternative. It just felt natural to get a Framework laptop and try running Linux on it.
I still have a Windows desktop for games and other things, I still use Mac at work. I still like the Mac for it’s power efficiency and it doesn’t get as hot. Linux has some annoyances here and there, like dbus locking up, or weird GNOME issues, or for a while my screen would artifact until set some kernel params, or the fact that my wifi card would crash and I had to replace it with an Intel card, but I’ll stick with it.
