Now that the FAA's mandatory drone registrations are open, how many people are rushing to sign up? Quite a few, actually. The administration reports taking over 45,000 registrations since the program opened up two days ago, on December 21st. In fact, the demand was sufficiently "overwhelming" that the FAA's site has occasionally buckled under the load. It's temporarily shutting down the site overnight (between the 23rd and 24th) to make sure that it can cope with the likely flood of registrations from people getting robotic flyers as gifts.
