We’re aware that some people are currently having trouble accessing the Facebook family of apps. We’re working to resolve the issue as soon as possible.
I don't have any apps at all. Just a pc & monitor. I think this is North Korea. They've had huge upticks in cyber attacks last few months. That my GUESS. Wonder if FB will ever say what is the cause of this worldwide disruption. Maybe our government may inform us? (I know nothing of Instagram)
