It’s interesting to know that even though the Internet is all one big connected web of sites, not everyone sees the same thing. For example, based on your location, Google directs you to a Google datacenter nearest to where you are, and the results that you get may be different from someone else living elsewhere in the world.
In addition, one other factor that location has is speed. So if a website is hosted in a datacenter in Singapore and a visitor from the US visits it, that visitor’s going to experience a slightly slower speed than someone in Singapore.
So I dug up a few free online tools that allow you to check your website speed. Some show you what speeds your website have from North America and South America, while some have a more international network.
