As another paying user of Kagi I wonder what prevented you from using another search engine for the six hours that Kagi was unavailable. Search engines are not like your email provider or ISP in that you're locked in.
The thing is, I never thought Kagi was down and thought that it must be a problem with my configuration or connection. That was how much I trusted in Kagi. I didn’t spend whole downtime online though.
Well, seeing that Kagi was down, I tried to switch to Google by doing "!g xxx" which gave me the same result than my previous "xxx" search.
I took me a few seconds to realize how stupid I was and then typing "google.com" in the address bar.
