Seriously, who cares about 5ms difference? Or even 25ms. I don't. And Asia is just used to longer latencies.
Edge compute became a commodity even before it was born.
The whole point of edge workers is to be able to provide very low latency all around the world... once you have that, it opens up whole new classes of workloads. Yes, 25ms doesn't matter for most current use cases.... but that is partly because the use cases that required lower latency weren't possible before.
I’d love to be able to (affordably) spin up a low-latency Windows desktop for a few hours at a time, that I could use for applications which don’t run well on my bottom-tier M1 Mac
