The server hosting this domain is a VPS hosted in Switzerland by Nimag network SàRL. Access speed from Asia is pretty bad, specially due to network latency on the pipes Singapore-US and US-Europe. In using a CDN to serve assets, we improve global page loading time in lowering the loading times of assets. The VPS has a good European connexion, there is not much need for visitors in Europe to use a CDN. The other reason, is to lower the traffic costs on the CDN level.

Everyone is aware of tools like speedtest.net to get a sens of the Internet connectivity speed to certain regions. While it works on mostly every device it allows you to test speed to only one server at a time. And is primarily meant to test the speed of your ISP. I wanted to test connectivity to several part of the world in an one click way, usable on multiple devices. The answer didn’t struck me at once, but it all can be done with some Javascript and mainly with the xhr object.
