Newest mac mini this started happening with the new os I think. but on all my browsers safari, firefox, and chrome. certain sites will not load at all or really slowly. facebook will not always reload on safari but may do better on the other two. but the worst is google search. it may fail on all the browsers even chrome. on chrome you will get a error but reloading usually works. like I tried to connect to swappa and none of the browsers would do it at all chrome finally did slowly. I have cleaned the cache and that helped for a few days.
