There is a lot of discussion on Internet, but some answers are more likely than others.
Is it a hack? No, this happened all over the world at the same time. Most likely it is triggered by facebook staff.

Is it a test tools for facebook developers? This is the most likely answer to what my quick experiments is. Not confirmed, but as an educated webdeveloper – this is the most logical answer.
Most important – you are not hacked, so no worries.
