Today at around 21:57 IST , Facebook faced downtime. It continued upto 22:15 IST. We've got a message showing that "We are working to get back to you soon" . Mark after considering to expand the business of Facebook has to work more to prevent such downtime errors. Some of the users are assuming that there may be some malicious reason for the sudden shut down of Facebook. Anyways Facebook faces black day twice in this year.
