Hello, I just answered a topic from two years ago regarding this subject:
From there:
Dude, I just have exactly the same doubt. My current scenario:
I’m from Brazil and I have one dedicated server on Chicago/USA hosting my Plex Server. The peering of my home ISP from Rio de Janeiro/BRA ↔ Chicago/USA is pretty bad so I paid for a VPS on Brazil that has a really good connection with the network where my dedicated server is located, I configured a reverse proxy (Chigago/USA → VPS on Brazil → My home) and now my experience is much better.
The problem: The VPS I paid on Brazil has a full duplex link of only 50mbps, and this can barely sustain 3~4 simultaneously 1080p direct plays. I had a simple idea, why not pay for the same VPS package again and set a second additional reverse proxy to my server on Chigago? I can do it easily, but how to get both reverse proxies being reached by plex.tv?
normally I would say to just setup a loadbalancer with hostname plex.domain and point the LB to the plex1 and plex2 hosts. problem as i see it is that each plex server is a unique device. so you have to claim both servers individually but what you really want is if i understand you correctly that you have both as single instance behind plex.domain?
that would some kind of active/active HA setup with a LB in front. never read that this is possible but it would be nice.
that would make it easier to create plex services with LB and DNS service routing based on geo ip for example.
let me know if you find something out…
