Yahoo Storage Outage
http://www.sportsgrid.com/nfl/were-sorry-yahoo-just-emailed-all-of-their-fantasy-football-players-this-apology/
"So what happened? At Yahoo!, we have giant machines called “filers” that process a lot of the real-time data and stats for us and for you. We do millions of calculations every hour for our games, and normally our machines can handle this with no problem. Recently, we discovered a hardware issue in one of the filers that caused the other one to overload. We replaced some hardware, re-configured the setup, and did some testing. However this Sunday – at approximately 12:15 p.m. Eastern – the new configuration failed. This created an overload on storage capacity and took the Fantasy part of our site down."
