This will only affect public auctions that are closing at night and into the morning. An auction like this one with 1 bid will be affected.
Here is the note from GoDaddy
Auctions will be performing maintenance starting on Friday, December 9, 2016, 11:00 PM Eastern Standard Time. Maintenance is expected to complete after 6 hours. Any auctions that are scheduled to end during this time will be extended following our maintenance window.
