I am looking for a least latency and max throughput region for Google AppEngine for users in Thailand. According to Cloud locations closest are Jakarta and Hong Kong. Tried to make sense of an underwater cables map information for my question. Could not put an answer together. What I am thinking is a test setup of 2 GAE applications behind a CloudLoadbalancer and measure user experience (somehow).
However, maybe someone was able to figure it out already? Is it Jakarta or Hong Kong GCP region which is faster to Thailand users?
