Ukraine region not available any more: while "ua-uk" URL parameter is still mentioned on search params page[1], it's not working. I didn't get the answers on DDG forum (now closed in favor of reddit), neither on /r/duckduckgo. I suspect this could be connected somehow to Yandex block. Anyway, currently can't use DDG for local search, sad :( [1] https://duckduckgo.com/params https://duckduckgo.com/params
