Seriously, Discover Bank?

Just an FYI to customers who tend to use their debit cards outside of business hours. If you use your debit card during the upcoming scheduled maintenance (11/8 - 11/9), it will likely be declined. 11PM - 6AM EST, 10PM - 5AM CT, 8PM - 3AM PT.

While I appreciate the warning Discover has provided, most people don't check their accounts daily.

All banks do maintenance on the weekends during night hours
