Facebook and Instagram get knocked offline... for about an hour

Snowmageddon might not be all that fun those experiencing it on the East Coast, but it could well be affecting the rest of us too. Starting around 1am ET, Facebook and Instagram were both inaccessible, as well as apps that require FB credentials. Tinder, for exmaple, also went down in the process -- globally. (We saw problems accessing servers across the US, Europe and Asia.) We've also seen Hipchat and, er, AIM also knocked offline at the same time. Snow in the servers? Or maybe it was a DDoS attack? We don't know just yet. Facebook and Instagram have just come back after an hour. Interestingly, as TechCrunch noted, Facebook's other app, WhatsApp went strong through out.

Update: Hacker team Lizard Squad took to Twitter to claim responsibility for the outage. Services are currently restored, but we're reaching out to Facebook to see what the official word is.
