I can't check my yahoo mail?

I got back from my trip yesterday. I was out of state for 2 days. But when I got back I couldn' tcheck my yahoo mail. I could log in just fine but when I click on my mail to see what I have it just says "internet explorer cannot display the web page". I have 2 other email account and the same problem is going on for all of them. How can I fix this because it is getting annoying.
