Problem with Viewing Yahoo Mails

I am finally online after doing a lot of errands today. The first thing I did was checking my inbox some minutes ago. As I was about to open my inbox, below errors occurred. These were the messages that appeared on my computer screen.

"Ouch!
The error, LaunchEmptyResponse, occurred when trying to connect to Yahoo! Mail.

To retry Yahoo! Mail... To proceed to Yahoo! Mail Classic...
This error might be temporary.
Go to Yahoo! Mail

To proceed to Yahoo! Mail Classic...
Click here to check your mail using Yahoo! Mail Classic."

I did tried it again and again but I can't still open my inbox. After maybe six times of trying it, I was redirected to my inbox. Another problem occurred, I can't open any mail. After trying it around ten times, I can finally read my mails. I have no idea why these things happened sometimes in yahoo mail. Thanks goodness that all went well again.
