This thread acknowledges that DJF was down for at least 30m on November 11, 2019 starting at 6:45 PM EST.

The reason is that the hosting company had an "internet based issue" that their engineers addressed. As expected DJF came right up afterwards.

If you noticed that DJF was down earlier than 6:45PM EST, please let me know as I intend to argue for credit from the hosting company.
