Do you ever wonder how fast your website would load in other parts of the world?
Just Ping is a great service for that, you can check your website ping times from various different places in the world. You can also use WatchMouse.com to check the actual loading times for your website in various different parts of the world too.
And if loads way too slow, you might want to think about having a server in other parts of the world. Web hosting services such as VPS.net allow you to do this as you can choose a datacenter between UK and the US.
I am also looking into having another server in UK soon through VPS.net to serve faster webpages in the UK. Well, I will have a DIY on that too so watch out for that.
