Anyone else having DNS problems in Lion? Things like forums.macrumors.com frequently break for me, where macrumors.com works fine, until I kill mDNSResponder - where it instantly starts working again. I've tried switching DNS servers to no avail and am currently using Google 126.96.36.199 & 188.8.131.52. A colleague who also just upgraded to Lion is getting the same thing on a number of websites. Is it a bug or perhaps something that went wrong with the upgrade? Any advice greatly appreciated!
