Yeah, I would be really miffed if there was actually something worth posting to twitter and the WiFi didn't work.
I agree that it looks as if a panel or repair section failed at the fasteners. If that's the case, there is a little risk of direct injury. Most of the danger would be from passengers over-reacting. To some extent the FAs can influence that, although there is always that small percentage that will panic about anything.
