Until last month Apple used netscape.com to provide the default home page to its Safari users. Apple made a change last month and until today the old page continued to work. Now, however, a user of Safari who goes to www.netscape.com is treated to a redirect loop (the previous URL was home.netscape.com/apple.adp). Oddly changing Safari's user agent doesn't solve the problem. Internet Explorer on OS X continues to work. For now it appears it's just the users of Safari who have to go without the Netscape Network home page. cnn.netscape.cnn.com which is not on Netscape's servers does still work for Safari.
