Nintendo is preparing a big multiplayer overhaul, probably for games in development in 2020: every task currently taken by NEX is going to be switched over to NPLN. It's currently in a preview phase, and the Monster Hunter demo was a way to test how it worked under load.

It uses gRPC servers hosted on GCP (or on AWS, with GCP in front) - it's fast, and it runs on multiple regions.

Looking forward to see the results of this effort, it's probably going to make the Switch's multiplayer much better than today's if it includes relay servers!

Nintendo is replacing its multiplayer server system, NEX (used in most, if not all of their online games since 3DS/Wii U), with a new system called NPLN.
The Monster Hunter Rise demo was the very first game to use this in public.
