Facebook Chat Down [UPDATE: Up and Running] – Following Privacy Lapse

Update: The geeks at Facebook were quick to get on top of things, hence the Chat feature is up and running. Kudos

In case you are wondering why your Facebook Chat isn’t working at the moment, it’s because Facebook disabled it. Mashable reports that Facebook Chat is now down for maintenance. It was presumably disabled following a report that exposed a Facebook security bug that allowed users to access and view friends’ live chats, friend requests and friends in common.

The report indicates that access to this personal information was accessible via Facebook’s privacy settings, with the Preview My Profile feature creating the loophole to access the private live chats of friends.
