This is a little project exploring the feasibility of using a service such as Globalping for geo location needs.<p>I had fun making it but please note that the current implementation is just a demo and far from a proper production tool.<p>If you really want to use it then for best possible results you need at least 500 probes per phase.<p>It could be optimized fairly easily but not without going over the anon user limit which I tried to avoid

Bit surprised this works. Latency variability is huge and sometimes quite disconnected from geo location. I recall talking to someone in NL and realised I've got better latency to NL content from the UK than he did. Presumably better peering etc.

How feasible would it be for the host under measurement to introduce additional artificial latency to ping responses, varying based on source IP, in order to spoof its measured location?

Amazing idea and execution, the sort of stuff I wish there was more of on HN.
