Google made a tiny change recently that is probably a big deal for people who need to work on this kind of stuff every day, but one that means little to nothing for everyone else.
Because the internet is worldwide and people in different places are best served with different information, the company used to use what's called a country code top-level domain redirect when you searched for something. This meant that your search results came from google.ng if you were in Nigeria, for example. This allowed the company to curate its results better to (hopefully) ensure they were more relevant.
