Facebook and Instagram networks were not accessible late Monday night and very early Tuesday morning.
The outage come on a night when many people probably expected to be sharing images of the blizzard affecting the northeast region of the United States.
It is unknown if high traffic in the Northeast might have indirectly brought down the social media network. Instagram showed a “5xx Server Error” at 1:00 am. CST.
