First few instances I tried are either returning no results, or only DDG results.

Error! Engines cannot retrieve results:

brave ( Suspended: too many requests )

google ( Suspended: too many requests )

qwant ( server API error )

I've run in to exactly that. By putting my SearXNG on a machine that also does NAT for a busy network, this can be avoided. This is definitely one instance where IPs from a colo are a bad thing and residential IPs are a good thing ;)
