But, AWS already launched a 3rd AZ in January: https://www.computerweekly.com/news/252433676/AWS-opens-thir... For example, Aurora is now available in Singapore: https://aws.amazon.com/about-aws/whats-new/2018/03/amazon-au...

And they are launching in Hong Kong this year: https://aws.amazon.com/blogs/aws/in-the-works-aws-region-in-...

How much latency improvement should we expect by moving from US-central (default) to Singapore?

Where are your users located? I built a tool to roughly measure latency between your browser and various GCP regions: http://gcping.com

Great tool! CloudHarmony is good too: https://cloudharmony.com/

I am very sad Hong Kong loses out all the datacenter project to Singapore. all due to idiotic government and regulatory. and connection from hk to sg isn't exactly great either.

Isn't that due to geography? I suspect many customers want to have one dc for southeast Asia and Singapore is in a better location than HK, esp if you also want to serve Indian customers from there (and potentially Australians). Customers with higher East-Asian traffic are likely to also have presence in Japan. I'd suspect HK demand is very regional, i.e. for projects based in HK.

Earlier quoted context omitted.

I mean the 3 datacenters in Singapore

Three zones doesn't mean three datacenters. Just means there are separate sets of power, networking etc.

Doesn't AWS still advertise that their zones are at least 10 miles or so away from each other? Does it turn out that this is just completely unnecessary or why doesn't Google follow a similar approach? Honest question, I was always wondering if there's a need for physically separate locations if you could have two completely separated zones on one lot.

Very cool! Most of my users are in South East Asia. But, I live in France. So, it would be great, if you can give an option to change my location to see the latency.

Don't we all? It's called teleportation.

Or VPNs. :)

It’s highly unlikely that Amazon (or anyone) can reliably find or build datacenter space that is high quality _and_ within a few miles of other such space across all the regions they operate. If they had gone to to such lengths they would clearly state that zones are fully independent from each other. Instead they only say that about regions.[0] So even though I have worked at neither company I’m going to say their concept of a zone is mostly equivalent — independent in terms of power and network domains but in the same building or at most on the same property. This allows them to have the low latency that is touted between zones of a specific region.
