I think that there may be an option in the Preferences.....your Google preferences....which permit you to select which page that you use as default.
My own Google page defaults to Google Thailand.
But there is a link to Google.com right on the page. I clicked it...and boom: I am on google.com, with a link offering to take me back to google.co.th, should I prefer.
I am signed into the gmail service....and I use an increasing number of Google services. Like news.
As the counselor points out, the price is right.
