I'd love to know how my sites behave in Frankfurt, Mumbai, SF, Sydney, etc.
Is pretty interesting.
If someone set up a postman style clone, but I could drop-down and run it from a server in ${wherever} - that might be worth something...?
Suggestions aside, look at the difference between HN and Google (measured in milliseconds):
us-east: 39 HN, 40 GGL us-west: 128 HN, 118 GGL europe: 186 HN, 109 GGL tokyo: 291 HN, 143 GGL sydney: 405 HN, 303 GGL
Kind of interesting, did not expect Googles latency to be that high in Sydney.
