Our game servers are running on Google Cloud Compute Infrastructure. We are running in all available datacenters to be as close to the user as possible to reduce the latency. Sending all our commands through the cloud allows us to make everything browser based, without any setup required, like downloading apps, connecting bluetooth or joining specific WIFI networks. We'll try to improve it even further later this year by introducing WebRTC.

Many of our games try to make up for the controller latency by adjusting the position of the player to where they would have been without the lag (Quickminds, AirShields, Hitparade).

I'm on a 300mb fiber connection and there was zero noticeable latency, very impressive.

WebRTC is the way to go here. Is your code open-source? I have plans to build just such a library, but could add it to yours instead.

It works smoothly and without much lag. The phone GUI is well executed.

at the very least, you should double your latency... which is not good for 3dshooter games
