Q: Safari will not all of a sudden connect to my yahoo home page.

I have multiple web browsers on my iMac but within the last two days, Safari will not connect to My Yahoo home page. All other browsers are ok. It will not connect by signing into Yahoo either in the browser or on the My Yahoo website. I keep getting a Safari cannot connect message due to redirects. I have erased history and cookies for a week, but have had no success. I am out of ideas where to look at this point since my other browsers connect fine.
