If you like browsing using firefox, there are plenty of add-on that make firefox very usefull. One of the addon I really love is flagfox. Flagfox is simple addon to show webserver location using the flag.
For example, you want to know where is candra.web.id is being located, just install flagfox then open candra.web.id. Flagfox will show you where the server being located.
Other information can be retreive using flagfox like wikipedia article about the country, Geotool to show the map (using google map) the server and whois to show you about server detail information.

just go to ht and try it.
