Yes, Taiwan is too far. I personally know of an adtech startup that is going through contortions because they need to stay below latency limits on specific ad exchanges and those exchanges are located in Singapore. Taiwan is certainly way to far for them.
There are other instances where I think additional ~50ms latency diff to from India to Taiwan matters much less and I am dubious if it is material. But what matters if that the difference exists and people believe it does matter.
We're squeezing by in Taiwan just about, if anything changes networking wise though we're going to have to diversify to more providers.
If you're struggling to respond within 50ms anyway then you're going to have a bad time with the added latency. Thankfully our 95th percentile is around 20ms.
We are however having to go into AWS for Aus/NZ which is a pain.
