Why is every Searx instance down when I try to use it?

I want to use SearxNG as my daily driver, and I added three instances to my browser’s search engines list. However, I find that all three are down whenever I try to use it, and I inevitably have to look at the list of instances and click the top one just to perform one search. Is there a way to “auto-route” my search through the most reliable instance or something?
