Facebook down for many users, even today

CBS - In one of its longest outages ever, Facebook was down for many users around the world yesterday and even into today.

So were its family of apps, including Instagram and Whatsapp.

About three hours into the outage, Facebook turned to twitter to say it was working on fixing the problem and that it wasn't a malicious attack.

Users reported a variety of problems--including not being able to send messages or not seeing some posts.
