Google's No Country Redirect, where you can visit google.com instead of your local Google site at google.com/ncr is not working for some users outside of the US.
Pedro said "Seems http://google.com/ncr (No Country Redirect) parameter isn't working anymore as of last week..." Same issue with many of the folks in the thread. But it is not dead for everyone, many are still saying it works.
This may be a sign that this feature is going away or it might just be a weird bug. I emailed Google almost 24 hours ago and still no answer, but they are looking into it.
Google did recently drop the country search filter and it might be that Google is doing away with this all.
Interestingly enough, Google's John Mueller joked on Twitter that now he has an excuse to expense trips around the world to test the search results in those locations.
@pedrodias Does that mean you can expense trips to each location to check? :-))— John Mueller (@JohnMu) December 21, 2015
