Facebook lost people's email notification settings

Last week, one of my friends told me that he got an email from Facebook saying that they have lost his email notification settings. “How can Facebook lose people's email notifications? Not possible” I thought. At first my friend did not believe that email, he thought it was a phishing email. Even if he checked the url in the email and it seemed valid but for some reason he still could not believe it.

But until he logged into Facebook and found the same message on the home page. So, the email was legit and Facebook had indeed lost his email preferences.



It is very concerning to me. How can a company like Facebook lose data? Millions of people put a lot of data on Facebook and how can Facebook not keep proper safeguard to make sure data does not get lost and proper backups to restore the data. It is not clear if a programming error or human error cleared all the data or did somebody break into the database/file system and cleared it out. I am not sure if it was just my friend or others got affected as well?

Did you receive similar message from Facebook?
