If you are located in some country outside US typing in Google.com you will be redirected to local Google domain. Google does it because local country domains are made to provide more relevant results to local country users, but it can be very annoying if you want to search some topic unrelated to country. I just find out that there are very simple solution to this problem.
There are alternative address for Google.com domain which you can use to always get to Google.com without redirecting to local Google domains.
Use this address: http://www.google.com/ncr (nrc – no country redirect)
If you use Google as your browser start page (as I do) you may want to type in this address insted of Google.com if you want to get rid of redirects.
