First of all, excuse me if this theme is not apropriate for this forum, but I wanna share it with you, as internet users, because I feel an improvement in the speed my web-pages appears when browsing.
I read this article, https://wp.catedu.es/zgzsur/changing-dn ... et-faster/, and I chose CLOUDFARE dns (1.1.1.1 and 1.0.0.1) and I feel the difference.
Give them a try, you are not gonna find problems and probably your feel the advantage.
