Search for 'credit card down' and you'll see very widespread reports of machines being down at Lowes, Shoprite, Taco Bell, Starbucks, Circle K, Home Depot, Whole Foods are just a few of the brands I've seen multiple twitter users mention, and the places being mentioned are across the country.

The Toast system is down, too.

Lots of people tweeting at company brands complaining that they can't accept cards. Lots of exasperated retail workers, too.
