LiveJournal was down

Although LJ was down on Jan 15th, my My-Yahoo Feed reader was able to show all my LJ friends' blogs without any problems. I click on some interesting article and it doesn't work because LJ is down. How was My-Yahoo able to show feeds when the LJ server itself was down? Any idea? Does it cache the results? If so how often does it refresh the cache. And more importantly, how many results does it cache. For example, my My-Yahoo itself has more than 70 feeds. Does it cache all that?! Someone from Yahoo please let us know. 🙂
