Yahoo! Mail is Down! - Error Code 15 - Joins the infamous failed services

After recent failures of GMail, Amazon Web Services, Twitter, and few others, Yahoo! has felt the urge to join this infamous elite group.

I am unable to access Yahoo! Mail and while accessing my account I am taken to a screen which tells me about Error Code 15.



Here's the message:

The Yahoo! Mail Team

I hope these companies knew how to run services without any hitches but that does look like a distant possibility. Would you have problems in trusting these services for running your business or for hosting your emails?

Is it too hard for these companies to protect a production environment from failing? Heck, I thought they tested it thoroughly before final deployment.
