I was surprised very much with this. I thought that it is a phishing email but I see the sender and I logged in to my account and found this message.
Oh! it's real! I don't know what's happen at Facebook.(wait for news) but it made the image of facebook look bad. The very big website lost their member data. How about backup system?
There is no backup for the data?
After I googled about this issue, many bloggers have commented about this too. Really I love facebook more than other social networking websites. I wait for the news to know what happen to the Facebook now?
