Oops – Facebook Loses Email Notification Settings for Some Users

While Facebook has experienced explosive growth over the past year, stories of technical issues resulting in lost user data have been rare. Facebook’s engineering team has done a great job building scalable and reliable systems on the whole.

However, some users have received updates from Facebook this week that their email notification settings have been lost. Some users whose settings were lost, like Rob Spectre, report that now all their email notifications are by default are turned on. Other users who’ve seen the problem have told us that all their email notifications are by default turned off.

Either way, resetting the 50 or so Facebook email notification preferences – plus dozens more for applications – could take a while for most users to fix.
