Safari can't find the server
Since updating to Yosemite and Safari 8.0, I frequently encounter the following problem: I am checking out the Apple web site, and click on a link inside the web site, and here comes an error message: "Safari was unable to open the URL ... because it could not find the server www.apple.com".
This happens with many other web sites. This is very frustrating, and I would hope that there is a solution for this problem....
