The glue records for the NS are set at 48 hours.


dig NS

;;           172800  IN      NS           172800  IN      NS           172800  IN      NS           172800  IN      NS


What happens if the NS aren’t back within 48 hours?

I am starting to see reports that in ISPs with very large numbers of residential users, customers are starting to press the factory-reset buttons on their home routers/modems/whatever, in an attempt to make Facebook work. This is resulting in much heavier than normal first tier support volumes. The longer it stays down the worse this is going to get.

I personally believe that the outage was caused by human error and not 
something malicious. Time will tell.

However, if you missed the 60 Minutes piece, it was a former employee 
who spoke out with some rather powerful observations. I don't think that 
this type of worldwide outage was caused by an outside bad actor. It is 
certainly within the realm of possibility that it was an inside job.
