I live in Australia and I recently went to Thailand for 3 weeks and was flying through Singapore.
Now I'm back in Australia and I still get .sg sites as the top results even though they are completely irrelevant:

I don't remember exactly, but it could be that I logged into kagi on one of my devices in the Singapore airport.
I expected to have the same search results as I had before the trip, namely mostly Australian and international websites, not a mix of Singapore and Australian ones.
