The Sainsbury's and Tesco ones happened on the same day (last Saturday), but the scale was very different. Sainsbury's were unable to take card payments nationwide. My local one said it was due to the internet connection in their store not working. It also affected planned deliveries, likely because the scanners they use to fetch and pick the orders didn't have a connection.
Sainsbury's blamed this on a botched "software update".
Greggs happened today and was card payment related but doesn't seem to be nationwide (I've not been to one today so not 100% sure if that's true).
